[1.] One line summary of the problem:
PROBLEM: various oops's in 2.2.19 SMP kernel.
[2.] Full description of the problem/report:
The machine runs along fine for a couple of weeks, and will eventually hang
with an oops. I have had this happen approximately 5 times to date with
different 2.2.x kernels, but have not reported it until now. The ooops's are
not always the same.

[6.] A small shell script or example program which triggers the
problem (if possible)
Not applicable. Cant reproduce easily. The oops's have been happening
anytime after 3 to 6 weeks of uptime.
[7.] Environment
Machine is an SMP dual PIII 500 machine with 768MB RAM,
Mylex DAC960 RAID controller in RAID 5 configuration with
5 active disks, 1 standby disk.
this machine functions as a postgresql (7.0.3) server. Nothing else signifigant
is running on this machine. The machine is running redhat 6.2 with all of the
released updates applied, and is running a stock 2.2.19 kernel that was
downloaded from ftp.us.kernel.org and was compiled on this same machine.
