OOPS on woody/2.4.18-bf2.4 #1 Mon Aug 4 00:43:03 UTC 2003 i686 unknown

Dear guru's,

I'm getting an OOPS on a recently installed Debian box.  Before upgrading to
the latest woody 2.4.18-bf2.4 it would crash hard, killing interrupt
handler.  Now, it gets an OOPS but keeps on running.  The problem is I
cannot run anything that looks at the process table, or that process locks
up.  These crashes happen between days and hours apart, seemingly at random.

The only other symptom I had noticed is that if I did a "find /", it would
occasionally pause for about 7 seconds, and processes blocking on diskio
would start climbing before returning to normal.  Almost as if it was
resetting the SCSI or IDE bus, but nothing was left in logs or dmesg.  I
left "vmstat 1" running overnight, and though it stopped functioning after
the OOPS, it was not during a period of high i/o or cpu.

The machine is SMP capable, but using only one processor currently.  Mobo is
Tyan Thunder LE S2510 (Dual PIII)

Why is it crashing?  Thanks in advance for any ideas.  Current plan is
memtest86, and installation of a kernel from an identically equipped machine
that is having no problems.
