    SubjectAPM poweroff

    Sorry if this is the wrong place, though I don't think it is...

    I've got a TMC 15VGF motherboard with a VIA chipset. (apm: BIOS version
    1.2 Flags 0x07 (Driver version 1.9))

    I'm using a 2.2.13 kernel, compiled with the poweroff on shutdown option.
    But when I execute halt -p (or poweroff) the kernel panics at the point
    where I expect it to powerdown. I copied the oops message by hand and
    then re-typed it once I had rebooted. I've included the ksymoops output,
    but I'm not sure where to go from here, is this a known problem, should I
    be able to find the problem using the ksymoops output ?

    Thanks in advance, and merry christmas!

    --James

    ps. My processor is a MAD k6-2 400, and I'm fairly sure the apm code in
    the bios isn't faulty, because the machine switches itself off when it
    gets shutdown from windows...

    -- ksymoops output --

    ksymoops 0.7c on i586 2.2.13. Options used
    -V (default)
    -k /proc/ksyms (default)
    -l /proc/modules (default)
    -o /lib/modules/2.2.13/ (default)
    -m /usr/src/linux/System.map (default)

    Warning: You did not tell me where to find symbol information. I will
    assume that the log matches the kernel and modules that are running
    right now and I'll use the default options above for symbol resolution.
    If the current kernel and/or modules do not match the log, you can get
    more accurate output by telling me the kernel version and where to find
    map, modules, ksyms etc. ksymoops -h explains the options.

    Warning (compare_ksyms_lsmod): module bsd_comp is in lsmod but not in ksyms, probably no symbols exported
