    Subject"Unable to handle kernel paging request" x 3
    Date
    From
    This is the 3rd day in a row i got an oops.
    The only difference this time was the machine had one postgresql running, with
    mailsnarf, vmstat, apache and inetd; without any load.

    The oops (passed through ksymoops 2.4) is attached, with the dmesg.

    Linux sol 2.4.1 #3 SMP Wed Feb 14 18:14:33 ARST 2001 i686 unknown
    The only module loaded is the megaraid.

    Please ask if you need any other info.

    Thanks,
    Alberto
    ksymoops 2.3.7 on i686 2.4.1. Options used
    -V (default)
