Ubuntu :: 9.04 Hangs Up On Kernel After Reboot
Sep 4, 2010
My old laptop has a broken screen. I tried using an external flat screen and win-xp would not run this screen. This is how I came to learn about Ubuntu. I loaded Ubuntu 9.4 and the computer worked with the external screen. The only problem was that during the boot process the (kernel text?) the white text on black screen over ran the edges of the external screen. Once the Ubuntu was loaded the window fit the screen perfect. Now my new problem. After a year of perfect use, the battery ran down and the computer shut itself off.
When I put the charger back on and rebooted the laptop, the ubuntu partly opens then hangs up on the kernal (white text on black screen) because of the screen overrun problem I can not read the text. I can boot still boot from the 9.4 CD. Is there anyway I can correct the problem by re-installing 9.4 but not wiping out my person data and files. In other words is there any way to repair the O/s that is defective, without losing my work?

I am an experienced Linux admin and have been using SuSE for many years. My development machine has had every version of SuSE since '02 and although it is a little old, is in good working order. (AMD
2400, 2 gig RAM, 160 Gig IDE disks - SuSE on disk 2) (OpenSuSE 11.1 with the latest kernel works perfectly. This install is on a spare HDD prior to doing a full install on my usual HDD.)
When I try to install SuSE 11.2 from DVD, the load kernel operation hangs at 97% (using both normal and safe kernel), however, I can install from live CD without any problem. I have tried the same DVD on a few "older" machines and had the same problem. I initially thought it was the actual DVD but re-burning has the same problem. I have also tried another DVD writer - same problem.

I am using Ubuntu 9.10. Every time I try to reboot my system it hangs. Shutdowns work properly. I've done multiple re-installations. Nothing I've tried fixes the problem. Does anyone have any suggestions?

The server runs# uname -r2.6.18-128.4.1.el5However, today I executed yum update kernel*due to security advisory. I was just about to reboot the system when I realized that it runs VMWare Server Instance that will most likely fail to restart after kernel upgrade (I had a hard time fixing it after previous kernel update). Now I want to keep 2.6.18-128.4.1.el5 after reboot.I see that new kernel is scheduled for booting:
# cat /etc/grub.conf
default=0
timeout=20

I am running 9.04 Server (standalone). It had been running fine since I installed in last autumn. Upon reboot, fsck of the root filesystem was forced and it hangs at the same point (16.5%) every time. I was able to break out somehow with cntl-alt-del but the boot was to a read-only filesystem. So I couldn't disable the forced fsck. Instead, I tried to fsck there. It started, but hung. I couldn't do e2fsck -v as it needed the device and, although I worked on UNIX systems for decades, I am not familiar with the /dev/mapper stuff.
Looking at other threads, all involving the desktop GUI Ubuntu, I tried some of the suggestions. Went into the BIOS to see what I could disable. I killed the serial port and similar. (Some said that onboard modems interfered with the checks in /dev.) I also tried to boot from my original installation disk. That does work.The suggestion is to choose "Try without any change to your computer". The problem is that is not available on the server installation, apparently only the desktop (GUI). I had install, check CD for defects, test memory, boot from first hard disk, and something like repair or recover a broken disk. I started the last of them, as it seemed to be the only option. It failed because it couldn't get a dhcp address. I could manually configure it (as it is hard addressed anyway), but I didn't want to start screwing up configurations not knowing where it was going, whayt it would ry to do, and risk losing months of hard work.
Without help, I think I will be forced to install the OS on a second drive, use that install to fsck the original filesystem on the original disk, edit the fstab (or whichever has the config) on the original disk to disable fsck, and return to the original boot.I am building this server for a nonprofit and have put in many hours writing mysql/perl apache cgi code for them as a free service and hate to lose it all and set back everything.

I'm on an HP Pavillion dv1000 laptop. I used a live CD to install Ubuntu 10.10 to an external USB hard drive. The install completed successfully, but after a reboot I am stuck on a black screen with a white cursor. Before that I see nothing but the initial HP startup screen. I am able to run the live CD without problems, and I have been running Ubuntu from a 4GB thumb drive (which I installed on using the same live CD that I used to install on my current external hard drive). I had no problems whatsoever running from the CD or thumb drive, so I can't figure out why the external hard drive would be so different.

Computer hangs and sometimes won't reboot.
When it hangs I have seen this message a few times:
o[4348] EXT3-fs error (device sda1) ext3_get_imode_loc : unable to read inode block_inode = 14720620 block = 58753255
Also when the machine boots up I get a message saying something about IOMMU should be set in BIOS, but I can not find any such setting in BIOS. I do not know if this is related to the hanging.
I thought I had a hard drive problem at first so I tried a different hard drive. Same problem.
The mother board is an ASRock N68C-S.
One other thing, where is the file located that boot up messages are written to?

fedora 14 did an automatic update and on reboot it hangs displaying the "f" before the login menu. The "f" is how I now feel......... I do "fn+f2" as it is booting and it displays the sequence of loading items which report all is "ok" until it gets to "jexec services" and then it hangs. I beleive the "jexec service" is a Sun Java item but I am not sure. I have been using Fedora successfully for a number of months and need to get data from the machine.

Have openSUSE 11.1 and (AFAIK) KDE 4 on an older notebook; worked OK for weeks, then booting became a problem and the OS seemed to go to sleep between keystrokes: now the cursor stops blinking, the clock stops running, and nothing happens after clicking a radio button until the mouse moves. Am now 25 minutes into a reboot, hung at "Unmounting file systems" but it also hung for a while when changing run levels. Is this related to the stability problems with 11.1 I've read about? Possibly KDE? Where would I adjust a config to use kde 3.5 rather than 4?

I have Dell Studio 540 desktop and Debian Lenny installed on it:
2.6.26-2-amd64 #1 SMP Tue Mar 9 22:29:32 UTC 2010 x86_64 GNU/Linux
The problem is that I can't reboot it. It just hangs after "Will now restart" message.
I've already tried: reboot=b, reboot=a, reboot=h kernel options.

The server hangs or reboots when I install Fedora 13 x86 (32-bit) from DVD onto a quad core server (64GB of mem, 16 cores). Sometimes it gets as far as starting anaconda before the hang or reboot. I've been trying different combinations of kernel options, such as vesa, pci=msi, irqfixup, max_add=3072M, noapic, nolapic, noirqbalance, maxcpu=2...
But whatever I do, it hangs or it reboots. The 64 bit versions of RHEL5.5 and RHEL 6 Beta2 installs without problems.

I installed Ubuntu in my PC alongside winXP. I downloaded the ISO and mounted it using a virtual image software (PowerISO used in winXP). I installed Ubuntu using wubi in a 20GB partition. During installation it asked me how much space should I give, I gave it 11gb. Everything went fine. I rebooted but now the computer hangs during startup. I went to verbose mode to see what the error is and found out that everything is ok. The last line that apears is "Setting sensors limit [OK]" and then nothing happens. I have tried every option (safe graphic mode/ demo mode etc etc) but the computer hangs.

Having a problem with my system hanging after updating Fedora 12. Here are my system specs:
Gigabyte MA770-UD3 motherboard
AMD Phenom 9950 Quad Core
6 gig Corsair DDR 800
1 x 160 gig SATA (OS)
1 x 500 gig SATA (data)
I have my system configured for dual boot with Windows 7. After installing F12, I can reboot with no problem. However, after I install the kmod-nvidia drivers, my system hangs on reboot. If I press any key on the keyboard, it will start to load, the freeze until I press a key again. I have tried both Fedora 12 x64 and i386 with the same results. Here are the steps that I took to install the kmod-nvidia drivers code...
Does anyone have any suggestions as to what I am doing wrong?

Ubuntu hangs at start up.Im running 10.10 from a wubi installation - without any problems since. Now, I select the kernel, do ENTER, then I get the blinking big dos-like cursor (still normal)but when it should show the list of "checks".( I dont know how this is called where it checks services, battery state and comments everything with [OK]) it suddenly hangs. All I get is a small blinking cursor, but not more. I need to power down and turn my computer on again, then it usually works.

I have an Ubuntu 8.04 server running 2.6.24-23-server. I have a godaddy account and I am trying to upgrade my os version to 10.04, which requires a kernel upgrade. I have tried ksplice but kernel 2.6.24-23-server is not supported. I have heard about screen sessions but I have not found it possible to reboot one screen while having the other screen stay persistent if it is possible.So the main question is how to update Ubunut 8.04 to Ubuntu 10.04 with out rebooting the entire server? Rebooting is completely not an option at the moment.

I see there are lots of messages about fedora 12 freezing.Actually I have such a problem with fedora 11 since I updated to kernel 2.6.30. My laptop, all of a sudden, freezes. Everything is freezed: mouse is not working, keyboard not responding (hitting caps lock produces nothing), can't switch to terminals, ctrl+alt+canc don't work. I can just push the power button to shutdown the system. BUT the hard disk activity is still going on. I can see and hear the sleeping daemons that cause some usual disk activity while the rest of the system is completely freezed.My system is a HP DV5-1025el with an AMD Turion ZM-80, Ati Radeon HD3450, 4Gb of RAM and 250gb HDD.I got fedora 11 regularly updated, now has kernel 2.6.30.10-105.2.23.fc11, but it is used to happen also with older 2.6.30 kernels, NEVER happened with 2.6.29 kernels. Video driver isn't the cause, since it happens with both proprietary fglrx and OSS radeon drivers.

I recently decided to venture into the world of Linux/GNU by installing Ubuntu.
Before installing, I had a 190gb partition for windows 7 and 45gb of unallocated space. Through Wubi, I used the advanced partition editor to make a 6gb swap partition and a 22gb root partition for Ubuntu. All went well, but when I rebooted, I was unable to choose linux.
I installed Ubuntu by using Unetbootin to put the Ubuntu ISO on my USB drive. After installing, I disconnected the USB drive, and I was unable to choose the linux kernel option on the GRUB menu. When I do, my system just restarts and presents me with the GRUB menu again. However, windows 7 boots up perfectly.
I'm assuming that GRUB is somehow trying to boot the linux kernel from the USB. How do I change it to boot from the installation I made on my harddrive?

It hangs after mounting my root partition, and switching to framebuffer. And ctrl-alt-del causes a normal shutdown - everything gets told to exit.
This where it hangs:

This is my config:

lspci output:

Based on the mainline defaults. I made sure ext4 is compiled in, SCSI, SATA and PATA support... sda1 is my root partition. sdb1 is a data drive. The drives are SATA.I need to rebuild from source to test some stuff for wayland.

I've been playing around in attempt to see how small a usable kernel I can build. The theory is that it should mainly be useful for preparing a recovery disk or some such thing; disk drivers and a few network drivers are what goes in.
I built the kernel with the attached config. It boots, reaches the hdd (if I specify root as /dev/sda5 manually), then dies when it tries to start Plymouth (something about catching a SEGV signal). What needs to be enabled to run Plymouth? Alternatively, has anyone managed to remove plymouth from boot on Maverick?
(That would require a modified mountall version, I know.) I'm using the mainstream kernel 2.6.32.27 sources on Maverick (yes, I know Maverick uses 2.6.35; but this does boot).
Hardware: Wireless-RTL8192SE b/g/n, uses an out-of-tree driver (r8192se_pci, from Realtek; Ubuntu builds in an older version of this driver); r8169 works for ethernet; ATI Radeon Mobility 3200 graphics, AMD Neo X2 cpu; SATA hd in AHCI mode.

I've recently upgraded to Natty (11.04).The problem that is now occurring, and reoccurring, is like this:- Computer boots, but hangs on a purple screen (nothing on it). Nothing happens, after 15 minutes or so I give up waiting and hard reset.- Boot via Grub (holding shift) into recovery-mode: works fine, but I want the GUI, so I reboot.- After reboot the system hangs again, as mentioned before.- Hard reset again, and booting a previous kernel (2.6.32.8 ): works fine!- Restart again, boots in most recent kernel (2.6.38.10): works fine now.- Try to shutdown/restart again, problem re-occurs every time. So I use the workaround with the extra startup with the older kernel again.and finally typing this.

The most recent kernel update, to version 2.6.38-11 has been a horror. It hangs on boot up. Sometimes I can get to the log in screen, then it hangs there as well. However, after 3-5 reboots (which is absolutely annoying to do when I just want to use my computer), it sometimes loads up finally. However, if I go to older Linux version in the Grub menu, then I can select 2.6.38-10 and it runs just fine.
So I am looking for a way to fix this problem, whether it be removing the most recent kernel update, or making 2.6.38-10 boot up by default. I noticed that the kernels are listed in the synaptic package manager, but I am afraid to remove the most recent one via synaptic. Is it as simple as removing the Linux version and headers I don't want, or are there other things I need to do in order to make 2.6.38-10 my default kernel at start-up?

I've noticed a bad behaviour with the latest 2 Fedora kernel releases:
- it happens with 2.6.31.12-174.2.19.fc12.x86_64 and 2.6.31.12-174.2.3.fc12.x86_64
- but 2.6.31.9-174.fc12.x86_64 is OK
The problem is as follows: Any kind of terminal application (any X based terminal and the console itself) hangs on certain operations involving colors from what I've seen
E.g. 'ls -F --color' as predefined in Fedora works but 'ls -F --color -a' hangs. Midnight Commander also hangs but works on black and white.
My terminal is xterm-256color under X and linux under console.
Other observations:
- it happens on a AMD machine but not on an Intel i.e. not all hardware is affected (couldn't narrow it more)
- same machine, same software stack but with kernel 2.6.31.9-174.fc12.x86_64 works OK

Pentium 4 3.4GHz
Used to boot to kenrel 2.6.31.6 for the past 2 months updating my system whenever i was asked to-NO PROBLEMS so far(till yesterday in fact)Mandriva yesterday, offered a list of system updates including the kernel 2.6.31.12 and the respective Nvidia drivers.Boot to that kernel computer reacted as usual and everything seemed to run properly. HOWEVER,when i tried to shutdown the system everything powered off(hdd-keyboard) except the CPU(and the power supplier).I restart(manually) the system boot in and try to reboot it-NO Problem-logout NO Problem but FAILED TO SHUTDOWN PROPERLY AGAIN.

I updated to the latest available kernel for Kubuntu 10.04 today (2.6.32-24). When the system rebooted, it refused to connect to my wireless network. So far I have been unsuccessful in persuading it to connect. ifconfig shows the existence of the ethernet connection as eth0, and Network Manager also seems to accept the existence of the ethernet port - so why has it suddenly chosen now to stop connecting to the wired network?

I would like to remotely reboot a computer (via ssh) to a non default kernel. If I just type reboot, it reboots to the default kernel. Man reboot(8) does not give any hint so I am not sure that is possible at all. I have found nothing googling around either.

Got a few multiuser systems for which scheduling an occasional reboot is a major PITA. Wondering if the ksplice solution is as painless as it sounds or there are tradeoffs.
