Freez and a reboot

[TheBlaze]

I upgraded from Lucid yesterday and I'm having big problems. The upgrade went fine boot to Maverick all is good. But after about half an hour everything froze and "capslock" an "scrollock" lights started flashing and then it rebooted. Everything was fine for half an hour and the same story. I left it at the login screen but it did the same thing. It's not a hardwarw issue, because I dualboot with windows and I could play Dragon Age for an hour with no problem. Does anybody have any idea what could be causing this, or how to find out. At first I thought it might be firefox but its clearly not because it freezes on login screen to.

Thank you for your ideas.

Hi,

Same symptoms are present here on my machine too. "Caps Lock" and "Scroll Lock" lights start flashing and then deadlock follows. But I have noticed that this always happens soon AFTER the packagekit (update check) icon appears on system tray ( or sometimes when I invoke apt-get from konsole) Interesting thing is, there is a "question mark" instead of system tray packagekit icon. There might be a problem with update notifier. Because, I don't get update notifications anymore.

This also happens with the clean Kubuntu 10.10 RC install.

Regards.

Re: Freez and a reboot

I updated twice since the upgrade and it'stil the same. Any ideas how to find out what's wrong? I have to use Windows for now. :-X

Re: Freez and a reboot

Based on oblivion's observation, I'm going to guess that his problem has to do with a glitch of some sort in (K)packagekit. Fortunately, this is easy to test.

(1) Start a konsole. Enter the command "sudo apt-get update" followed by "sudo apt-get dist-upgrade".
(2) Enter the command "sudo apt-get install muon". You could also substitute "synaptic" for "muon", because it is tried and true while muon is still comparatively new, but synaptic will drag in a lot of GTK stuff that you may not want, and muon is fairly compact.
(3) Enter the command "sudo apt-get remove "update-manager-kde ". If that doesn't help, you can try removing "packagekit" and "kpackagekit" as well.
(4) Restart your machine and see if I guessed correctly.

Re: Freez and a reboot

Booted only in console mode and waited for it to happen. It did. It said there was a kernel panic. Don't remember the rest. On wikipedia it sais that this is equivalent to bsod. What do I do now?

Re: Freez and a reboot

Boot to single user mode (recovery). Type:

apt-get -f install

If there are any unconfigured packages, this will/should fix that, and maybe your issue as well.

Re: Freez and a reboot

apt-get -f install

Did nothing. I tried booting an earlier kernel. Will report if it helped.

Re: Freez and a reboot

Like I said: I selected 2.6.32.x kernel instead of 2.6.35.x in grub. 7 hours later every thing is O.K. where do I report this problem?

@Snowhog:
I posted the comment.

@oblivion:
Does this (using a different kernel) help in your case as well?

Re: Freez and a reboot

New problem after today's update:
I I select 2.6.35.x kernel it boots but freezes (kernel panic) after a while (~30 min) - so, no change here.

If I select 2.6.32.x kernel, I can't get past the "Kubuntu" splash screen. I think it has something to do with the nvidia driver, that was updated. The update said it didn't generate something for the running kernel (2.6.32.x), because source was not installed (or something similar).

So now I can't use Kubuntu.
Help?

Is that a laptop? Do you have any thermal monitoring where you can observe the temps? One possibility is that the CPU is overheating, triggering a thermal shutdown. If that's the problem, you'll need to look into the ACPI options for your CPU/motherboard.

Re: Freez and a reboot

@dibl: this is a desktop computer. It's probably not a hardware problem, because Windows and 2.6.32.x kernel doesn't give me any problems. I can play games for hours (Windows) and never had any problems with Kubuntu. The only problem I have is with 2.6.35.x kernel.
So:
Windows: fine
Kubuntu 2.6.32.x kernel: fine
Kubuntu 2.6.35.x kernel: kernel panic

The new problem is, that after I upgraded today (in hopes that the problems with 2.6.35.x kernel would go away), I also cannot boot with 2.6.32.x kernel. My suspicion is that the problem is with the Nvidia driver upgrade. It boots to "kubuntu" splash screen and waits there. The computer still responds to "ctrl+alt+del" and reboots. But I don't know how to get to console, or how to fix the Nvidia driver.

Re: Freez and a reboot

I just noticed that Desktop Effects are hosed up on my system, at the moment. Probably we are in some transitional situation -- I don't advise doing anything drastic until we get to the released system, in less than a week.

As far as booting your 2.6.32 kernel, do you have a boot menu? If yes, then simply highlight the 2.6.32 kernel, and press "e", and remove the "quiet" and "splash" options, then press Enter and then "b" to boot it. You may need to reinstall your Nvidia driver -- you didn't say how you did that, so I can't say how to reinstall. If you used the jockey-kde thing, then you'll need to boot into the recovery console and run "Fix X". If you installed the downloaded proprietary driver, then you can do that from the console as per my guide in the "How Tos".

Re: Freez and a reboot

The problem is that the package "linux-headers-2.6.32-25-generic" is not in the maverick repository. And without it jockey-kde cannot build the module. So where do I get the needed package?
