    SubjectOoops, linux 2.6.1
    From
    Date
    I don't know if anyone gets anything out of this. I tried running it
    through ksymoops, but got just weird results.

    Hope someone sees what's going on here.

    Best regards,
    Stian
    ksymoops 2.4.5 on i686 2.6.1. Options used
    -V (default)
    -k /proc/ksyms (default)
    -l /proc/modules (default)
    -o /lib/modules/2.6.1/ (default)
    -m /boot/System.map-2.6.1 (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.

    Error (regular_file): read_ksyms stat /proc/ksyms failed
    No modules in ksyms, skipping objects
    No ksyms, skipping lsmod
