In an earlier message you suggested replacing __generic_memcpy_tofs
with the version from 1.2.13 and it worked. By the time this message
makes it off this machine, I will have had 24 hours of continuous
error free (as reported in syslog) operation on my problem machine.
It passed its previous 1.3 record over twelve hours ago. (Considering
how much useless legacy code is already in the kernel (xia fs, ext fs,
etc.), it would be nice to also include the slower memcpy routines as
a special option for people with braindamaged hardware.)

Adding that to the accumulated 16 days of error free uptime on the
other four boxes I had 1.3.84 running on (they've been running 1.3.85
all day today, also without error), and I'm already rethinking my
opinion about the relative stability of 1.3 kernels.

Just to be sure that it is indeed the Cyrix chip, I'm going to have it
replaced tomorrow.

$ uptime
9:35pm up 1 day, 0 min, 9 users, load average: 0.10, 0.08, 0.23
