    I am getting the following oops while trying to update the microcode of a
    PII@266mhz using the microcode update driver. Below is the output of
    ksymoops. This was built using egcs-1.1.2.

    Also in case it matters I've applied the ide-2.2.18 patch so I can use my
    Promise ATA66 controller and the latest reiserfs patch..

    Regards,

    Aaron

    ksymoops 0.7c on i686 2.2.19pre3. Options used
         -V (default)

         -o /lib/modules/2.2.19pre3/ (default)
         -m /usr/src/linux/System.map (default)

    No modules in ksyms, skipping objects
    Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?
