Thread: box still freezing while booting Linux (not Windows)

  1. box still freezing while booting Linux (not Windows)

    Hi,
    ~
    I dual boot a box and I would like to find out why it crashes
    unexpectedly while using Linux/Debian/knoppix (Windows appears to work
    just fine or at least better)
    ~
    All of a sudden my screen goes blank (black) and all I see on it is
    the blinking cursor on the top left corner of it, as it my system was
    trying to reboot by itself, but it actually freezes at that stage
    ~
    I was recommended using "acpi=off" and "noapic" as part of my boot
    parameters,
    ~
    comp.os.linux.hardware: "box freezes without apparent rhyme or reason
    .. . ."
    ~
    which I have been doing as you could see from my dmesg output:
    ~
    BOOT_IMAGE=linux init 2 acpi=off noapic bootfrom=/dev/hdd2/knpx_5.1.1.iso
    ~
    I have taken it now as a general troubleshooting/debugging challenge.
    ~
    Which utilities could help me in finding out the cause of my box' crashes?
    ~
    I think running a script to produce outputs from "dmesg" and "ps -efl"
    would help, but I was wondering which other utilities could I use as well.
    ~
    Could you for example dump the content of the BIOS preferably in text
    form? Either directly or coding some assembler or C?
    ~
    How often should such a script run?
    ~
    Any prior art you would like to share with me about troubleshooting
    hardware with Linux utilities?
    ~
    Here is what I got:

    Hi Albretch!

    I am no expert, but it looks like the boot process stops
    as the video subsystem is waking up. Perhaps a framebuffer
    issue? Adding kernel parameter vga=normal (or knoppix-txt)
    might help.

    You need to find out what it's trying to do when it crashes. One way
    (if it's mounted "/") may be to reboot off a boot CD and check
    /var/log/dmesg . If it hasn't, then maybe various boot options at a
    boot CD's bootloader prompt may be sufficient to get you up.

    The recommender believes those to be common causes of failure.
    Reasonable, but if they don't work, they're probably not it. You might
    have multiple failures, so you should keep those options until you've
    made it work once.

    > Which utilities could help me in finding out the cause of my box' crashes?


    A boot CD. http://sysresccd.org makes a good one.

    > form? Either directly or coding some assembler or C?


    There might be a way by dding /dev/mem , but as BIOS manufacturers and
    versions are not the same everywhere, I'm not sure it would do you much
    good.

    Disable everything until you get it to boot. Then re-enable things a
    few at a time until you find the culprit(s). You can do a binary search
    if your bookkeeping skills are extraordinary, but the time spent keeping
    track of it all may far exceed the time saved rebooting unless you have
    a _lot_ of reboots.

    i915 sounds like an Intel video card. Is that correct? If it's firing
    that up, is it starting X? (ctrl-alt-backspace to kill X; if nothing
    happens you're probably not in X.)

    sure you know top, but do you know atop
    which is like top, but more
    ...the default
    install includes a logger which takes a snapshot of system processes,
    memory in use, network traffic etc etc etc every [mumble] minutes and
    saves the log for 28 days..

    and you easily set the snapshot interval and log save time by editing
    one config file..

    its footprint is small, and it is 'nice'...i'm sure if it runs each
    10 minutes you won't notice....and, my guess is as long as you watch
    the log file size you could run it each minute...and, maybe get an
    idea of what is doing what and when..
