Ubuntu :: Hard Freeze During Or Shortly After Boot?
Mar 3, 2010
My problem is that within a few minutes of booting the machine, it freezes. The keyboard and mouse do nothing; the keyboard LEDs do not light up. Whatever is on the screen stays there - X or a console. Ctrl-Alt-Del does not work; neither does Alt-SysRq-REISUB. The machine stops responding to ping and won't accept any remote connections. I have to do a hard reset with the power button.
Sometimes it happens during the boot process; sometimes it's a few minutes afterward, and I get to look at log files for a while until it stops responding.
Here's what I've tried:
It happens in recovery mode as well as a regular startup. It happened when I booted from an Ubuntu Server CD and did rescue mode. I ran memtest86+ and it completed successfully with no errors (and it didn't freeze) It doesn't happen if I just sit in the grub menu for a while. I've looked at what log files I can; there's nothing that looks like a severe error, and it fails at different times during the boot process, so it doesn't seem like whatever's going wrong is getting logged. It happens with the latest kernel I have (2.6.31-19-generic), as well as the oldest (2.6.28-16-generic) It seems like there must be some hardware issue, but I'm not sure where to start looking.

So my Dell latitude E6400 running fedora 12 (2.6.32.11-99.fc12.i686.PAE) is usually connected to a big screen (1920x1200).
Now each time I boot, X becomes unresponsive shortly before or after login for a couple of minutes, and then goes back to normal. This happens both with and without connection to the big screen.
The error messages associated to this seem to be like this, my /var/log/Xorg.0.log is cluttered with them :
Code:
I normally start my computer in the morning, walk off for some tea, and come back when X is functioning, but when I'm in a hurry it's pretty, or very, annoying ... drinking tea / coffee to wait for a computer to start is something people did in the 90s, it shouldn't be default behaviour in 2010 ...

I've been getting a random hard freeze, in both windows and linux, so I'm pretty sure it's not a software thing. I've run memory diagnostics in windows and it came out fine, I'm not sure what other diagnostics I can run. what tools can I run in linux that might help me further diagnose the problem? I haven't installed any new hardware, and I blasted the inside with some compressed air to err on the side of caution, but I still have problems. i'm running the latest ubuntu ver btw

I have a fresh installation from the demo ISO image of F14 running on an Acer TravelMate 4200. The system is a Dual Boot with win Vista. Windows Vista runs without any problems but when using F14 a kernal crash constantly occurs and it then hard freezes or hangs and the machine needs to be cold booted. There is nothing in particular that I am doing either, the problem happens when the machine is idol or when I am working in various apps.
The F14 system is completely up to date running kernel version 2.6.35.13-91.fc14.i686. The following error below is from the automatic bug reporting tool and I have reported this using the tool:
Package: kernel
Latest Crash:Sat 04 Jun 2011 14:55:00
Command: not_applicable
Reason: BUG: unable to handle kernel NULL pointer dereference at 000000f8

I've been having problems with Ubuntu/Kubuntu (I switch back and forth) freezing shortly after booting and logging in. I installed 9.10 a few days ago (fresh install, new hard drive). I installed all of my packages, and everything works fine except this freezing bug.
If there is not a freeze within a few minutes after startup, then there so far has not been a freeze at all (so, if everything is fine after a short time, then everything will continue to be fine). I'll try to add some information here that will be helpful: I dual boot with Windows 7, which is installed on sda1. Ubuntu is on sdb. There doesn't seem to be any problems with this. I have an Nvidia 9800 GTX+ graphics card (I use the proprietary driver). 8 GB Ram, Intel quad 2.66 CPU.

I'm trying to use Ubuntu 11.04 on my desktop computer after not having it for a few years (I've actually been waiting for new releases to fix this since it started around 9.04, with no such luck). However, it freezes within minutes after logging in just after a fresh install (triggered by trying to do pretty much anything beyond just moving the mouse, opening menus, etc., although I was able to apt-get install a few packages through terminal with no problems and run update manager) with no explanation. I was able to install Ubuntu through the Alternate installer, however. Normally, I would just search the internet (including this forum) (I've solved several problems that way), but this problem wass too broad for me to find anything useful and specific.
Actions before freezes include browsing the web with Firefox, trying to mount NTFS drives in Computer, and particularly predicatably when opening any non-terminal package manager program. Freezes occur reliably whether in full-featured mode or in Safe Mode.
Initially, I thought the problem was related to my USB Microsoft Wireless Laser Mouse 5000, but replacing it with a standard non-USB mouse fixed nothing. The Microsoft Mouse does however freeze up by itself on separate occasions, leaving the system operable with the keyboard (independent of whatever the other problem is).
I'm only able to post this from Windows XP. Text Dumps (links): Hardware Info Summary generated by Speccy dmesg dump after freeze and hard shutdown collected from WinXP) Xorg.0.log after freeze

I'm running Jessie 64bit, and after installing the latest image and fully updating it, I get screen freezes using gnome, most oftenly when i press the start button to access gnome app grid. System becomes unusable and I have to hard reset. Just in case, I installed linux firmware from nonfree repos, but the issue persists. I don't use any exotic hardware:
Code: Select all00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor DRAM Controller (rev 06)
00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor PCI Express x16 Controller (rev 06)
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
00:03.0 Audio device: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller (rev 06)
00:14.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB xHCI (rev 04)
[Code] ....
I'd say it's related to graphics, but I don't know how to get around it...

I've been running F@H on my system for a while now, these specs:
ASUS Rampage Formula
Q9450 @ 3.6Ghz
4GB DDR2
8800GT 512MB
Fedora 12
Running various different nvidia drivers, with working 3D, and running the latest nvidia drivers with cuda for GPU2 folding + SMP folding.
I decided to add a 9800GT to the machine for more folding PPD, and I've run into some issues.
Firstly there were problems starting X, it would hang as it started or even before it started, so I switched to RPMFusion's repo drivers which have the VGA_ARB patch applied. This now gets me into X and working 2D.
The problem I have is, although the system is completely stable running folding on all four cores, SMP, 24/7, as soon as I start anything involving 3D (such as glxgears) it will run for 3 seconds then hardlock the machine. I mean seriously lock it, no switching to terminals, and an ssh session into it from another PC dies.
Its the same with any other driver that will boot into X with the VGA_ARB patch (talking nvidia binary here).
Both cards work perfectly individually, AND both cards work, including full 3D in Windows 7 when together, which would tend to rule out a hardware fault.
Here is my xorg.conf

I am attempting to boot both OSX 10.6 and Enterprise Linux 5. This is what I did: sudo yum install grub.x86_64
[Code].....
Now, however, when I restart and choose to boot from the Linux partition, I receive the "loading GRUB stage 2" message, and then I receive the standard GRUB menu where I should be able to just press enter and proceed. However, instead of letting me choose a boot option, it just freezes. It is hard frozen. Nothing works. I have two keyboards hooked up, and neither the arrow keys, nor any other keys will cause anything to happen. Even after waiting several minutes, it remains frozen, even though the timeout is set to 10. What on earth is causing this freeze? I am using the exact same instructions in my grub.conf that work on the grub command line. If I delete grub.conf, then it goes back to the GRUB command prompt where I can manually type everything in, and it always works.

I installed OpenSUSE 11.3 a few weeks ago. It freezes 10 - 15 seconds after startup. I got a brief, but incomplete reply to what I thought was another related problem on the forum (OpenSUSE 11.3 / Mozilla Firefox freezes upon moving the mouse), but it turns out that the problem is neither the mouse nor Firefox. It freezes without doing anything special.

lost all sound on flash after firefox updated (or shortly thereafter)
in other words videos and the like are silent (which is a kind of a blessing, really).
10.04lts 32bit
firefox 3.6.8 - (for ubuntu - canonical 1.0)
flash 1.0.10 (tried r&r already)
external usb sound card, desktop system
sound works great everywhere else, including mp3's on web through firefox. i searched the forum, of course, but didn't find anything that seemed relevant or up-to-date.

I have a computer that serves as a mp3 playlist for in the kitchen. I just installed it, and now the sound is not playing correctly. When playing a song with rhythmbox, it will crash after about 40 seconds. When I play it with Amarok, it produces sound for about 40 seconds and then the sound stops, although Amarok keeps playing.
I did the following to the system:
- I put an other computer completely in an other case (Motherboard, harddrives, memory, CPU, Power source (you know the box that powers the motherboard and harddrives, etc.) (Yes this has to be done )
- As for the front panel of the old case, the wires could not be attached to the motherboard, so I only attached: 'HD led' and the 'Power button', but I could not attach the front speaker to the motherboard.
- I reinstalled debian etch
- The motherboard had onboard sound in the back, so I didn't install an audio card. However, when I first booted with debian, there was no sound coming from the port. Therefore I installed an audio card in 1 of the PCI slots.

I just downloaded and installed Ubuntu 10.10 Netbook Edition for my Toshiba Tecra A4 laptop, but the system first froze at the default desktop picture (nothing was loaded except the arrow). Tried restarting only to find it frozen on the purple boot screen again with only the mouse arrow loaded (I can move it around).
Note: The same thing happened when I tried to boot Ubuntu from CD (without installing)

I have two internal harddisk. Harddisk 1 has ubuntu, fedora installed and harddisk 2 has ubuntu installed. I normally connect either one, and use it. How can i always keep connect both harddisks, and at the start, select from which harddisk to boot? Or it's not possible?

I have a Toshiba Satellite A205 laptop 2GB RAM, running Meerkat 32bit. Used 2 previous versions of Ubuntu also.For the past few months, about 75% of the time, on boot up the screen will freeze before I get to the login screen. No key combos (ctrl alt backspace, alt prnt screen, REISUB) work, I have to take out the battery, unplug and restart. It always boots normally the second time, whether I boot normally or attempt repair.I recently installed Linux Mint 10 on dual boot, and the same thing happens with Mint.I connect to the Internet via wireless, not sure if that is significant or not.The problem does not appear immediately after installation, but only after updates and a couple reboots.

I set the auto timeout on my dual boot machine to 1 second. It will not allow me to select anything but the default option I had set, which is Windows XP. I would love to be able to get back into Ubuntu, but I can't.I tried logging in through a live CD I had for Xubuntu v9.1, but I was unable to successfully run "Startup Manager" to change the timeout back to 3+ seconds.

When I first boot up it gets to the checking sensors, then freezes and the screen flickers all the time. I have to do a hard shutdown then when I turn the computer back on everything works normally in fact the boot time is greatly reduced! And so far the system has worked fine after the 2nd boot.Anyone had anything similar?

Seems that I have been having a problem with the initial user login on Ubuntu 10.10 Netbook. Whenever I try and login the normal way (from standard gui login) my system comes to a standstill and I have to switch to command line (ctrl+alt+F2) and restart/shutdown my computer in that fashion. The only way that I can login and actually see my desktop without any hint of my system freezing up is by booting into the ubuntu recovery Console using the dpkg function to remove any broken packages, select boot normally (where I have to login through the command line), and manually startx.
Originally I was running an x64 version of ubuntu desktop 10.10 but I switched to an x86 version of netbook due to many incompatibilities in software and trouble finding x64 software for my system. When I was on Ubuntu Desktop I had a similar problem where it would freeze at login as well but I fixed it by removing compiz & compiz-core. I tried that with this version of the OS but had no luck because it said that compiz was not installed.
Not a major issue, just somewhat annoying that I have to resort to other means to login
PS: My computer is a Toshiba P500-026. Some stats are listed below in my signature if its relevant to my problem.

I have a dual boot configuration (WinXp and Ubuntu 9.10) on a PC (my video card is an ATI Radeon 4850), i have been configuring ubuntu for the past 5 days and everything was working fine. Today i installed Screenlets (through synaptic manager), and i was adding a screenlet when the screen froze. I could move the cursor, but couldn't click anything. I left it for about 5 minutes to see if anything changes, and since it was still frozen, i did a hard reset (restart from the button).
In the grub menu i chose the normal linux boot (not the recovery mode), it loads up the welcome splash screen (with the tribal sound and the bar moving), and then the little circle cursor appears, turns into the normal arrow cursor and it hangs. I can move the cursor, but the screen is stuck with the ubuntu splash screen.I restarted (again from the button) and went into recovery mode, but in the recovery console i can't select any option from the keyboard (i tried hitting the cursor keys, enter, nothing happens). I hit ctrl+alt+delete and it restarted the system (so the keyborad does function). In XP i found a recommendation to restart the Xserver, so i rebooted in the Ubuntu splash screen, hit ctrl+alt+F2, logged in, typed the command i found:
sudo dpkg-reconfigure -phigh xserver-xorgrestarted (sudo reboot), and got to the splash screen, which after playing the tribal sounds, turned semi-transparent (i could see the desktop wallpaper, taskbars and a black rectangle where my cairo-dock should appear), but again it freezed, no cursor. I hit ctrl+alt+F2 to go into console mode, and uninstalled screenlets (since it was the last thing i installed before the initial freeze).Screenlets uninstalled properly (i used sudo apt-get remove screenlets) so i rebooted, but it still freezes at the ubuntu screen splash (this time it wasn't transparent, just the standard screen splash). So i tried getting into console mode again, but this time my screen displays lines in a lot of colors, randomly (probably a failure from the video adapter)

I am running a Dell desktop with Windows XP Home Edition, which is up to date. My security suite is the Comcast-branded version of Norton 360. Following the directions in a Smart Computing article, I downloaded wubi.exe and ran it. I get the options screen, used the default partition of 17 GB, chose a password, and then I'm directed to reboot. I reboot and get the bootup option page. So far, so good. But then I have a problem. I click on Ubuntu and then I see a white three-sector circle against a black background. It pulses a little bit for a few seconds and then nothing happens. It just sits there, with no hard drive activity. I waited for a while, with no activity, then shut the PC down, deleted Ubuntu and re-downloaded everything. Still have the same result.

However i've decided to kick the nasty habbit that is windows. I've just installed Ubuntu 10.04 onto my HP Pavilion dv6-2020sa. Its a full install no partitions (i jumped straight into the deep end) However when i start her up, she gets to the loading screen of Ubuntu and the Welcome sound, blurts out of my speakers, but then repeats and repeats before stopping... the system then freezes, keyboard and mouse stop responding. Running from the Live CD works fine. I was reading through the forum and understand i need to get the boot info script, so here she is.

I just bought an Asus TS mini server. It has an Atom CPU (N280), and an Intel 945 chipset.
I installed Ubuntu Server Edition 10.04, that went smooth.
But on first boot, I see it hanging just after it mounts the swap. Now I don't think it has anything to do with that, the problem seems to me that at that point, it also switches the video mode. I guess that's where the problem is caused. It just freezes, no kernel panic, no reaction to the keyboard.
The system is dual boot, and the other OS is Windows Home Server. I put an ext fs driver there, and tried to read the logs, but don't get a clue from there. In particular, syslog doesn't even exist. Also no X log.

So I have recently been making attempts at setting up my RTL8192SU chipset usb wifi. After struggling to set it up by following the steps on this link: [URL]../url?sa=t&jUyXQukrfIw After doing this I had no idea what it was supposed to look like but It did display several warnings along the lines of "warning: cast from pointer to integer of different size" I continued following steps as another error occurred "cp cannot stat autoconf.rtl8712_usb_linux.h" I then entered sudo modprobe 8712u and my screen went black i was forced shut down . Upon rebooting I found it also would lock up if my usb device was plugged in It will boot with it unplugged but as soon as it is plugged in again it will lock up my system and send it to a black screen.

I am using Ubuntu Lucid Lynx 10.04 (64 bits) in my Asus U30JC laptop (Core i3 M350, intel 4500MHD + nvidia 310M with nvidia Optimus, 4GB RAM). I am content with Lucid and I don't want to upgrade to 10.10 for now. However I read that the new 2.6.36 kernel has some good improvements, such as improving system interactivity while intensive I/O (such as copying large files), and improved energy management for i3/i5 processors (which I hope translates into more battery time, which is a problem of Ubuntu vs Win7 in my laptop).
I discovered I had 2 options: compile the kernel myself, or use the Ubuntu Kernel PPA (maintained by the Ubuntu Kernel Team). I decided to use the PPA, so I added it to my software sources and installed the generic"linux-lts-backport-natty" kernel (2.6.36-1).
Package installation went fine, and after reboot, I could log in to the desktop no problem. Everything seemed fine, but after a few minutes, the system freezes completely: mouse did not move, none of the indicators moved, even Ctrl + Alt + F1 did not work.Where is the log file where there might be a message related to the freeze? Do you think that the kernel developers would try to fix a bug that probably only affects people running the 2.6.36-1 kernel on a distribution that was not built around it?

I'm migrating from XP to Ubunta 11.04. My PC: Toshiba Sat A30-921 L/top CPU: Pentium(R) 42.84GHz RAM: 512Mb Display Adapter: ATI Radeon 9000 IGP K/board: std 102/103 PS2 Pointing Device: Alps PCMCIA Adapter: ENE CB1410 Cardbus Controller Wireless Adapter: D-LINK GDWA 610
The installation went well from start to finish. Made it dual boot with XP. Hooked in the Eth cable & went online right away. Then enabled the W/less network adapter - all OK. Using 'Classic', so it's just normal screen after boot. Problem is random 'Freeze' or 'Hang Ups'. It's hung 12 - 14 times in 2 days! K/brd T/pad frozen out. Only recovery is to use master power switch & reboot. NEVER hung in XP in 7 years! (done other bad things though) Does Ubunta have switch like Cntrl + Alt + Delete in Win?
Tried many combinations but to no avail. I've tried quite a few Linux flavours (from Live CD) & they all displayed the same fault!! Before it hangs, I've been able to browse around Ubunta Apps: Places: System: Firefox: Internet: etc. Where do I start to track the problem down? I'm vaguely familiar (XP) with Terminal & cmd line processor but dont know any of the codes used.

I locked the screen, came back, typed the password, screen remained black, though cursor was visible and moving. Nothing I could do to rejuvenate the screen. Had to switch to tty6, sudo shutdown -r now. Then, on reboot obtained kernel selection, it proceeded to displaying kernel messages, but froze on sdb, after 3 secs. I figured it was the usb, so turned off, removed usb cables to external hard drives, but again it froze saying something about firewire mouse, the mouse is also usb. I tried several times, but no matter what kernel I chose, I couldn't get it to boot. So I loaded puppy live cd, but now it can't access some parts of the disk. I was running utorrent and the folder with partially downloaded files can be accessed but there's nothing there (there was), and some folders can't be accessed at all.
