Thread: System freezes after update to 11.2

  1. #1

    Default System freezes after update to 11.2

    I upgraded my Dell 2.53G machine from 10.3 to 11.2 (KDE desktop). Everything seemed fine for the first day. Then the whole desktop froze. No screen update, no keyboard, and, though you could see the mouse move, clicking didn't do anything. The only way out was to pull the plug.

    After multiple attempts at fixing it failed, I repartitioned the disk and tried a "clean install". Everything worked for about 2 hours. The system is currently frozen. The harddrive is quiet. The only "3rd party app" was Adobe Flash, pulled from the Non-OSS repository.

    help.

    Next time don't "re-install", try checking forum & buglist in Bugzilla.

    Does the CAPS Lock key do anything when it freezes?

    Do you have another computer you could try ssh into the box and see if it's X that's wedged?

    Try turning off any Desktop Effects, and see if the problem goes away.

    Enable the "Magic Sys Req" key in YaST, then whilst holding CNTRL-ALT-SysRq type R, E, B, I, O, S

    Magic SysRq key - Wikipedia, the free encyclopedia
    Linux Howtos: Tips and Tricks -> Magic SysRq Key

    Better luck, if you can find out if it's just X (usually is), then you can make much better bug report.

    I just turned it back on - the screen is black. It came up a couple of times yesterday but hung up on shutdown. So it's had multiple hard resets & if the first time was any indication there are now corrupted/missing files

    otherwise - no desktop effects (beyond default) have been loaded. I do have another computer - I'll see if I can SSH a little later.

    I had to do another re-installation. The file system was too corrupted to fix. This time the system lasted about 15 minutes before freezing up.

    hitting Cap Lock does nothing. No light flashes on the keyboard.
    Couldn't connect to it using SSH - possibly the network connection has been lost.
    I did a hard reset and tried the Ctrl+Alt+SysReq REBIOS (kinda hard on the fingers so it took a couple of tries) which rewarded me with a "keyboard error", a reboot, and now I'm back to a black screen and no system response.

    I'm going to try another version/distro and make sure I haven't got a hardware problem. 10.3 had been falling apart on me, so maybe it's more of a hardware thing.

    You might want to try running memtest86+ on the system overnight (or even
    for a few days) and see if it finds anything. Should be on your openSUSE
    media as an option when you boot from the media.

    I didn't find memtest86+ on the disk. A search of openSUSeFactory gave me a couple of manual links that are no longer valid (404 errors) and a one-click install that just brings up a text file.

    Found the utility & ran both hard drive & memory tests. The machine passed just fine.

    Installed Ubuntu 9.04 (with ext3) on the machine & so far it's working okay.

    Installed Ubuntu 9.10 (with ext4) on an equally old machine & had it lock up minutes after it came up, right after loading Firefox.

    Are there any known issues with ext4 on older disks? any settings that need to be changed?

    nope

    on shut down - I left it for 2+ hours today - it hangs unloading the NIC. Did a hard reset, loaded SAX and had the screen flash a couple of times before the whole thing died again.

    How long did you let it run its tests for?
