Ubuntu :: Sometimes Crashes On Boot / Shutdown?
Apr 23, 2011
My system sometimes crashes on startup/shutdown. No idea what causes it
This is my info:Kernel: Linux Mewtwo 2.6.32-23-generic #37-Ubuntu SMP Fri Jun 11 07:54:58 UTC 2010 i686 i686 i386 GNU/LinuxUbuntu version: Ubuntu 11.04 (Note: This also happened BEFORE upgrading to 11.04)All the info i could get is in those pics (This happened on boot but I also have crashes on shutdown):[URL]I couldn't find those logs anywhere else in /var/log so I guess it happens before the log files are opened

I accidentally powered down in the middle of a session by removing the wrong battery from my laptop (a Motion Computing tablet), and ever since that happened knetworkmanager crashes with a segmentation fault on startup. I have uninstalled it and then reinstalled it from an openSuse 11.4 DVD I made a few months ago, but it still crashes on startup. Ifup says it connects to the wifi (Wayport Access @ McDonalds) I have available, but browsers don't reach the internet while Ifup is connected, so I can't sign on and get access to anything more recent. Is there some file I ought to delete,or some other software I ought to delete and reinstall?

I've been running Debian Squeeze for the past couple of months. I decided to use a ReiserFS (not sure if it's relevant) and had a few problems where I had to hold the power button to shut down the computer. After that the system was not the same and froze from time to time (long periods of freezing) forcing me to hold the power button to shut down the computer, again.
Now, after /dev, /sbin...etc... not being found root not exiting, I have decided to do a new install, however, after several attempts at setting up new partition tables, deleting data on the HD and re-installing, I have failed. Maybe someone can give me some input... here are is my /var/log/syslog from when I ran the Debian install disk: pastebin - syslog - post number 1941832 (I think the end is most relevant).
In the mean time I am going to delete data on the current partitions (if I can) and try to re-install.

Strange problems and I don't know if they are related. This is Ubuntu 10.4 32 bit on a Toshiba Qosmio x505-q875 laptop dual boot with Winblows 7. One drive bay is a 64GB SSD with windows, my root, usr, and swap partitions on it. The other is a 1TB drive with the home partition.
First Problem: After the Grub menu disappears (defaulting to Ubuntu) about 25% of the time nothing happens. No harddrive light blinking, no cursor, nothing. Everything just stops. I have to use the power button to reset it. Happens several times in a row occasionally. I've never had this happen with Windows.
Second Problem: Sometimes Ubuntu doesn't see the sound card at all. The speaker icon is grehyed out and when I go into sound preferences, it doesn't list any sound device at all. Rebooting fixes it. This happens maybe half the time.
Last Problem: This one happens when the sound doesn't work. When i go to shut down the system, the hibernate and suspend options are not in the shutdown menu, and when I do shut down, it only logs me off. Even at the log on screen, if I tell the system to shut down again, nothing happens. I can log back on it that means anything, but shutting down again has the same effect.

I have a weird problem. Sometimes Ubuntu freezes when I'm booting up, sometimes not. I would say 2 out of 3 times it crashes, all other times it goes fine. I alway get past the GRUB bootscreen, then it starts loading. Towards the end or so, all of a sudden all disk activity stops and the screen hangs. Ctrl+C, Ctrl+Z, Escape, whatever buttons I press, it doesn't do anything.
I removed the "quiet" and "splash" boot options in GRUB so I could see in detail what is loading, but this doesn't make any more sense then before. The lines of text are always a bit different every time it happens so I can't really pinpoint when it goes wrong. Anyway, I don't see anything wrong with the output on my screen, I guess the real problem is not displayed.
I also tried booting into recovery mode. Also here this is strange. Sometimes I make it to the recovery screen with the options (resume, clean, netroot, ...), sometimes it crashes before that. When I get the recovery screen I choose "resume", this usually works and then I use "startx" to go into graphical mode. However, at other times, when I choose "resume" it freezes even before I get a login prompt.
So please guys, tell me, what is the problem here? How do I find out where I should start looking. Ubuntu sometimes freezes and when it does it doesn't alway happen at the same place as before. I know only 1 thing for certain, once I'm fully booted I don't have any problems whatsoever, everything seems to work flawlessly.
I am running a dual boot system with Ubuntu 10.10 and Windows7/XP. I am running kernel 2.6.35-24 (also tried 2.6.35-23, but no difference). I have an i5 CPU, so 64 bits. If you need any more information, just ask.

I have installed a cluster computer with 10 nodes . The manufacturer is HP . All nodes and the master node have redhat enterprise linux installed in them . When I shutdown the nodes from the master terminal using "shutdown -h now" they get shutdown . But they dont get completely turned off . This issue bothers me when the power supply is given , all nodes boot up simultaneously generating a huge heat .
Thing to note : When we shutdown our PC they get completely turned off . When the power supply is given , a press on the Power On button is required to boot the system. But , why does it not happpen in the case of cluster? Is there any other way of completely turning off the nodes from the master terminal ?

We may edit some values for GRUB from /etc/default/grub to modify the way that computers boot up and shutdown.My question is how to make such modifications for boot and shutdown. For example, suppose I want to display two splashes one during booting and the other during shutdown or I would like to acpi=off during booting and then acpi=force during shutdown.

For the past few days, my Ubuntu server (it is a desktop that functions as a server, Desktop installed) have been very slow.
Today, it stopped responding to ping, I could not SSH into it (once, I managed to come so far that it asked for my password, but I got timed out) and I could not connect via VNC.
I switched it off, to boot it up again. Post completed, and the screen went black, before the white text "Read Error" appeared on the screen.
I shut it down again, waited a minute or so, before switching it back on. This time, the "read error" did not show up. The "text only" startup for Ubuntu showed up, so I hoped it was all okay. It turned out it wasnt.
I have some pictures:

The top lines are code...
Any ideas on what could be the issue here, and how to fix it?

I have a small but annoying problem... I have two scripts that I want to run automatically one at boot and one at shutdown. For the one at boot I tried to put it in rc.local or to create a file in /etc/init.d/ based on the others files in the folder but nothing worked... I need it to run system-wide and not once a specific user is logged in.
For the script at shutdown I don't know how to do it but it can be user specific or system-wide I don't really care. I am running Ubuntu 10.10 64bits with kernel 2.6.35-24-generic
PS. I should add that when executed manually both scripts works perfectly well and I don't need those script to run continuously in the background, just run and quit.

I was stupidly compiling code on my netbook with 10% battery left. The CPU ate up my battery reeaally quickly and it did a hard shutdown while still compiling.When I boot up, the Ubuntu loading screen shows up for about two seconds and then it goes to a completely black unresponsive screen. I have a live install on my thumb drive, but I don't actually know what I need to do to fix whatever broke.Edit:Oo, something happened. When I pressed a key the screen filled up with a bunch of stuff I don't understand. But the last two messages are:
[ 450.807328] Fixing recursive fault but reboot is needed!mountall: Disconnected from Plymouth

I had to shutdown the computer while upgrading from Lucid to Maverick as it froze(bug in X11) and then when I start the computer I get kernel panic messages. I used a LiveCD to backup my files and I was wondering if there is a way to log in or reupgrade the Ubuntu in some way from the liveCD.
I don't want to do a fresh install as there are a dozen things I had installed and configured in my system the last 1-2 years.

I have a small issue of Xorg. Every time I boot the ubuntu 9.04, the X will crash immediately after it started. Then, it will start again and shows the login interface. It went well after the second login. I don't know what caused this since there is no error message in /var/log/Xorg.0.log and /var/log/gdm/*.

first of all I would like to say that Im not a very advanced Ubuntu (8.04 Hardy Heron) user. I have used it a couple of months, and got a long with it fine.. Yet, suddenly everytime I boot the Laptop the screen is Black with white lines, (no the monitor is not broken). When it asks me to chose a O.S. I have tried different ones. I can get into recovery mode without problems. Yet, when I start any other version (Ive got different ones, .16,.17 (I dont know why)) it freezes at the login screen. I can move the mouse but the caps lock doesnt even work. Sometimes (1 in 20 times) I do get to login, but after about 2-5 minutes the computer freezes.. (again i can move the mouse but nothing else works). Thats why I wont be able to use Gparted or any other programs to completely delete Ubuntu! I dont have another pc, so I wont be able to download that either.
What I have tried is reinstalling Ubuntu, yet it just kept the other Ubuntu versions no the computer. What I would like to know from you guys, how can I delete everything that is on my harddrive, so I can use the Ubuntu CD to reinstall?And yet another question, what problems could there be with my computer? I don't have windows, could it still be a virus? What parts of the laptop could cause this problem?I know that I have been quite repetitive throughout this post, I just want to cover everything.

Now, this is the case:
Yesterday, i tried to boot up my laptop but the battery was uncharged and it was unable to boot ubuntu karmic 64 bit. so i tried to plug the charger as soon as possible but when i looked at the screen, there was a huge black blank screen. so i had to restart it manually by pressing the power button. Now, i can see the grub screen, i can choose one of three kernels and the Windows. But only Windows can boot but the others doesn't. And also, grub timer does not work not. It does not count down to zero and autoboot the default os. I tried to reinstall grub but everytime , i got problems. Here is what i tried to do. In another try here, i failed again. In chroot, i could not "apt-get install" as it said i wasn't connected to internet (but i was), and in another try, it could not find p/rmonct /mnt/etc/resolv.conf.

Whenever I start my PC, the information of 'First Boot device' in BIOS changes from hard disk to CD-Rom. It happens with new start, I mean, if I restart my computer after resetting First boot device to hard disk, then priority does not change. Just as I switch on computer, a black screen appears with the message:
CMOS - checksum error - defaults loaded
press F1 to continue, DEL to enter setup
Recently it used to happen, that PC was not reading my hard disk containing GRUB. I have 2 hard disks. I switched the power cables of two hard disks. After that, both hard disks were shown by BIOS but the above mentioned error started appearing. Also grub takes too much time to load. It takes almost 20 seconds. Earlier I was using 'Puppy Linux'. In that, Grub was loading in fraction of second.

I've installed xUbuntu on a machine I will be using as a file server. Everything is fine except one thing. If the server suffers an improper shutdown such as a loss of power the next time the machine boots it gets to the GRUB2 boot menu and then waits for a keyboard input.As this machine runs headless with nothing connected other than a network cable and power lead and is tucked away under the stairs it's quite an inconvienience to go to the machine and plug in a keyboard so I can press enter.Is there some way I could force the machine to boot as normal without stopping at the menu ?

I have an 80GB HDD where I installed Windows XP first and then Ubuntu. The thing is that whenever I shut down my computer and then turn it back on (wether it's right away or a few hours later, or the next day), I get the GRUB screen where you have to choose Ubuntu, but after that just a completely black screen. I then have to force a shutdown, then turn it back on, and it works. Whenever I restart it works too, this seems to happen only after a shutdown.
Specs:
Dell Dimension 4600
P4 2.8 GHz procesor
2GB RAM
ATI Radeon x1650 video card
80GB HDD

During boot-up and shutdown of Fedora-14-x86_64-Live-Desktop.iso live USB, I just see some graphical stuff. What needs to be done so that the screen shows text messages about what's happening during boot-up and shutdown?

I have recently created a KDE 4 desktop using suse studio, it boots up fine on my machine, but doesn't shutdown!!
On my mum's laptop, which I will be using it most on, (it's windoez) it won't start KDE 4 at all! I can use the console, but I wanted to impress her with the amazing GUI and Compiz. And you can't make presentations or browse the web in a console, can you?
And sudo poweroff and sudo shutdown -h now don't work either!

I have installed the ubuntu 9.10 and the pc already have 2 win 7 OS and 1 win xp I installed the ubuntu from win xp every thing go just fine but in win 7 boat loader it detects the 2 win 7 OS , previous windows ( the xp )and the ubuntu which fails to load from win7 boot loader ( the first problem ) but it is present also in win xp boat loader so when choosing older windows the win xp bootloader let me choose between windows xp and ubuntu which works fine when choosing it the ubuntu bootloader appears with ubuntuubuntu safe modewin7 bootloader
the second problems that choosing win 7 after restarting the pc from ubuntu fail to open it begin loading with the windows logo and then just shutdown the whole pc as if i have unplugged it! the only way to let it open is to choose older windows>>> ubuntu >>>> ubuntu bootloader >>> where there is win 7 bootloader option it returns me again to win 7 bootloader but this time the windows load complete ( mostly but may shut down also!)

I experienced what i perceive as the craziest thing during 2 years of using ubuntu. About some months ago, I have two ubuntu installed on my HP-mini netbook: ubuntu 10.04 64 bit (CAElinux) and kubuntu 10.04, and run without problem.
One day, the netbook's battery run out of charge and I forgot to plug it in. The ubuntu, as usual, went to hibernate, but without harddisk noise, so I forced it to shutdown by pressing power button (as i think it is not normal). What happened later was the partition of 10.04 was broken, it could not boot, it even affected another partition as the netbook couldn't boot kubuntu 10.04.
I try to run liveUSB and CD of both distro and the liveCD/USB boot stopped on loading screen. So I try another linux distro: PCLinuxOS, which was able to boot but took very long time. The partition of ubuntu 10.04 could not be accessed.
After installing PClinuxOS in replace of kubuntu, I scanned the ubuntu 10.04 partition and the partition was fixed, I could access the partition and could load to ubuntu 10.04, but it took very long time. Here how it loaded: first: blank screen with blinking cursor, then ubuntu load screen, then back to blank screen with blinking cursor, then it showed numbers and sentences, like some scanning works. It took long time before login screen appeared (about 10-15 minute, while the prevously normal boot time in my netbook was less than 1 minute), but once its done, the ubuntu worked normally. This also the case in the PClinuxOS and the reason it load very slowly.
After this, I try to boot the liveUSB of various linux distro, and found some could boot while the others not:
Able to load with unusual slow boot time:
PClinuxOS (latest)
Ubuntu 8.04
Fedora (latest)
Linuxmint 8 (based on ubuntu 9)
Can't load
ubuntu 10.04 and 10.10
kubuntu 10.04
latest linuxmint
The liveUSB boot could take 1 hour. I also try the latest Puppy, Gentoo and OpenSuse liveUSB but it couldn't boot, and it likely the liveUSB problem. I made the all the liveUSB with unetbootin. The ubuntu 10.04, 10.10, kubuntu and the latest linuxmint could not boot even after I scanned the ubuntu 10.04 partition. There was no problem with the liveUSB as it would load normally on another computer. I think it is just the variant of ubuntu 10 that is not being able to boot.
I was not content on this slow boot, so I try to format the two partition of ubuntu and PClinuxOS (there are another partitions though), and installed ubuntu 8. But it also happened to boot slowly as the previous ubuntu. Then I replaced it with linuxmint 8, and the same occurred. So I try to install windows on another partition, and it boot normally.
The question is, what is happening. Why do the forced-shutdown-of-ubuntu-10.04 affect another partition, to the boot of another distro? If my HD was broken, the Windows would load very slowly too right? Yes, in SMART Data (from disk utility) it showed "few bad sector", but i think this is not related to the slow boot. The ubuntu 10.04, 10.10, kubuntu and the latest linuxmint cannot boot until this moment. I am thinking there are some informations planted on my computer, that twist it to load some distro slowly, and prevent it to load some others. But where and what? (I almost arrived to the thought that this is supernatural!)
Because of my long story up there (as I think it must be reported), the conclusion is:
1. Ubuntu 10.04 on my netbook was forced shutdown (by me)
2. It caused the partition broken
3. After fixing the partition (by scan, but I forgot the command), it took very long time to boot, but the ubuntu itself run normally
4. It also affected the boot of another distro (slow down the boot time), but Ms.Windows boot time is normal
5. It also caused ubuntu 10 (and its variant) to not be able to boot from liveCD/USB
6. It also caused me going crazy
Now im gonna format the whole HD in hope of ubuntu 10.04 (and later) could boot again, but shall it fix the problem? (as formatting the previously ubuntu 10.04 partition did not solve the problem). Or should I buy another HD (or even computer) to install natty!

My system is a Gigabyte GA-P35-DQ6 with Radeon 5770. The system was rock solid and everything working fine until the latest update I applied 30 minutes ago. The system is stuck on the little circle icon before the login screen.
I'm not able to ssh or telnet to the machine to check the log files. I edited my grub.conf a while back and I don't seem to be able to call up the recovery kernel. I can read up on the grub options.
