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)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.1/ (default)
