Thread: Computer Crashes and I dont understand root cause - see system log.

  1. #1

    Default Computer Crashes and I dont understand root cause - see system log.

    Hopefully someone can guide me on this annoying issue.
    OpenSuse 12.1, see hardware detail in my signature.

    I did some searching and it was thought that it could have been the latest FLASH update.... but I uninstalled it and the lockup are still occurring.

    I can use the pc for some time and if I walk away and come back later it will crash, last line being the watchdog....

    I don't know if the watchdog is related, and the last line in the log is
    that it is running. Or do you see something else in the display?

    A watchdog is some hardware and daemon that checks if the cpu is locked.
    For example, a daemon has to be called by the cpu every second, and reset a
    counter; the hardware access that counter and decreases it. If the OS gets
    stuck the daemon does not run, the counter is not reset, and the count
    reaches zero. The hardware sees that and sends a pulse to the computer to
    force a hardware reset.

    This way the machine will never lock for long, as if an operator is there
    to press the button.

    You might have such a watchdog enabled not intentionally.

    How would you check?
    Is there a specific application?


    amazingly I have been "up" without crashing for some 6 hrs now.
    did you see anything funky in the logfile that you would be concerned with?


    thanks for your time

    The watchdog in the log looks to be normal. It is related to rtkit and pulseaudio. I glanced at the log and nothing seems abnormal to me.

    So you need to tell us a lot more about this computer to really be helpful. I doubt a Flash update, loaded into your browser would be the cause of a delayed system lockup. In fact, most ofeten in older computers, its just due to memory problem.

    I did find a few curious things in the listing:

    Code:
    1. 06/03/12 02:07:08 PM LINUX-PD kernel [ 1.036136] cpuidle: using governor ladder
    2. 06/03/12 02:07:08 PM LINUX-PD kernel [ 1.036139] cpuidle: using governor menu
    This has to do with extreme low power settings, most often associated with a Laptop computer

    Code:
    06/03/12 02:07:08 PM    LINUX-PD        kernel  [    1.178576] ata1.00: limited to UDMA/33 due to 40-wire cable
    While this error is associated with a desktop and using the wrong IDE cable.

    Code:
    06/03/12 02:07:08 PM    LINUX-PD        kernel  [    2.324389] [drm]  nouveau 0000:01:00.0: Detected an NV50 generation card (0x0a5000a2)
    This seems to indicate an nVIDIA video chipset which if true can cause a problem when not using the nVIDIA proprietary video driver or perhaps a newer kernel version with a better nouveau driver. Your listing has MUCH BS due to the nouveau driver.
    Code:
    1. 06/03/12 02:07:13 PM LINUX-PD nmb[1984] Starting Samba NMB daemon ..done
    2. 06/03/12 02:07:13 PM LINUX-PD smb[2004] Starting Samba SMB daemon ..done
    Looks like you are using Samba I guess.

    Code:
    1. 06/03/12 02:07:14 PM LINUX-PD vmware[2120] Blocking file system#033[71Gfailed
    2. 06/03/12 02:07:14 PM LINUX-PD vmware[2120] Virtual ethernet#033[71Gfailed
    Perhaps you don't have VM support enabled in your BIOS setup?

    Code:
    1. 06/03/12 02:07:23 PM LINUX-PD dbus-daemon[792] **** pci ADDING /sys/devices/pci0000:00/0000:00:00.0
    2. 06/03/12 02:07:23 PM LINUX-PD dbus-daemon[792] **** pci IGNORING ADD /sys/devices/pci0000:00/0000:00:00.0
    This nonsense goes on for a long time and not sure what it is telling us about your startup.

    Code:
    06/03/12 02:14:15 PM    LINUX-PD        dbus[792]       [system] Activating via systemd: service
    Still using systemd as it is not disabled.

    Code:
    06/03/12 03:20:01 PM    LINUX-PD        dbus-daemon[792]        (packagekitd:14135): PackageKit-Zypp-DEBUG: zypp_backend_destroy
    This also goes on a while, showing some problems.

    While you are worried about the end, I suggest there is more before then, but more computer hardware info including age and condition can be helpful to know.

    I have VMware installed, wasnt aware of any specific bios settings for it.
    Yep I use Samba

    What is systemd?
    looks like it should be a part of the 12.1 opensuse os.

    On older systems I have got to ask. When was the last time you really cleaned out your system? Computers have lots of fans and fans fail and suck in dust into every where. I suggest that all PC's be cleaned out once a yer with a can or two of duster spray, best used outdoors in the bright sunlight and disconnected from all of its cables and power. I normally unplug and re-seat all memory, adapter cards and cables, one at a time. I blow out all heat sinks and in general remove all dirt from the PC. When I take it back in and reconnect it, I leave the side panel off and turn it back on. I use a flash light to inspect each fan to make sure it is rotating. Be careful and do not dismiss the need for such a cleaning on any PC older than one year old, particularly if it has never been cleaned before. You might want to invest in an 80 pin IDE cable (40 signal + 40 ground) for your blu-ray DVD burner or reader. If you can't find anything else, you might want to consider replacing, or upgrading the memory.

    After all of the above, you can look into upgrading your video driver, but make sure its for a clean PC:

    Installing the nVIDIA Video Driver the Hard Way - Blogs - openSUSE Forums

    LNVHW - Load NVIDIA (driver the) Hard Way from runlevel 3 - Version 1.45 - Blogs - openSUSE Forums

    S.A.N.D.I. - SuSE Automated NVIDIA Driver Installer - Version 1.46 - Blogs - openSUSE Forums

    +1 ! !

    i don't see any info about system temperature in your log...you should
    (if hardware allows) enable logging of CPU temp, at least (have you
    installed and enabled [the software package named] "sensors"? [its in
    the standard repo, i think])..

    when cleaning, be sure and blow the junk out of the power supply (blow
    from inside the case and out)..

    AND, although your power supply is a hefty critter, even it can wear out
    over time...and, eventually cause strange problems ("crashes") which
    don't point to an understandable root cause..

    "I have been "up" without crashing for some 6 hrs now" may go on for
    many hours and if suddenly the power supply delivers a tiny microsecond
    of too low power, or no power, it will be boom time again..

    by the way, when you say "crash" what do you mean?
    does the machine power off? (totally off, nothing moving, whirring?)
    or the screen freeze but you can move the mouse?
    or screen freeze with no mouse or keyboard input?
    or, screen and inputs frozen along with the num and caps lock LEDs flashing?
    screen blank, but num lock LED can be turned on and off with the "Num
    Lock" key?

    any of the above and you can Ctrl+Alt+F1 to a terminal and then log in
    as root, and then kill X with "init 3" then issue "init 5"?

    if the "crash" leaves the machine powered on and keyboard inputs are
    accepted: have you tried shutting down with REISUB? or, how are you
    regaining control.

    does it ever crash when the external drive is not connected?
    or, if not being used with the samba supported devices connected?

    oh, and when it is shut down for the cleaning, and the panel is off:
    *gently* disconnect and reconnect all the connections to the motherboard
    and disk one at a time...remove and replace the RAM..

    if after the cleaning and cable/RAM contacts 'polishing' (from the
    remove-reinstall) you still have problems whose root cause is murky,
    then i'd *guess* you have a weakening power supply or a CPU overheat
    problem....the former can be tested with a power supply tester, and the
    CPU overheat is often cured by removing the old and applying a fresh
    application of CPU grease/paste between the CPU and cooler...

    let us know how you get on....please. . .

    I have never used one. It would be a kernel thing. And it should reboot the
    machine, not crash it.

    I will look into the sensors.
    I cleaned out the computer and it wasnt that bad, still a bit dusty.
    Disconnected video, ram, drives and reconnected them.
    Set the 4 internal fans (to the case) from Low to MEDIUM

    the following will happen:
    nothing on screen...
    pc still on
    caps lock and scroll lock will blink at 1/s
    there is no response from the keyboard
    I can shut the computer down by holding the reset button.
