Good day, all,
I'm running 2.4.20-pre11 on an SMP Athlon system. System details
are at:

(30 second summary; Dual AMD Athlon(tm) MP 1900+'s, 2G registered
ECC ram, 360G raid array on a 3ware raid card (raid 5 across 4 120G ide's,
dual 3C980-TX onboard nics, noapic, rack mounted.)

In addition to ps hangs that I've posted to this list before (Nov
11th, Subject: "2.4.20-pre11 crash: kernel NULL pointer dereference in
proc_pid_stat."), I've found a problem with swap errors showing up in the
log:

These showed up before userspace died (again :-) yesterday. The
system successfully passed 7 passes of memtest86 a few weeks back.
Cheers,
