Description Ed McKenzie 2000-12-27 03:24:19 UTC 
Running bonnie over nfs reliably causes the nfs server to die. The first
oops is typically kswapd (!), followed by the knfsd threads. Syslog output
from one of these crashes follows this report.

Both the client and the server are running stock 2.2.16-22 kernels. The
client is running the smp-i686 kernel, and the server is running up-i586.
/etc/exports is fairly vanilla (/home shared as (rw,secure,no_root_squash)).

Since kswapd tends to die first, I assumed this might be memory related,
since the server only has 32mb. However, I've shut down everything besides
nfs, and the problem persists.

Kernel oops log attached.

Comment 2 Ed McKenzie 2000-12-27 09:00:48 UTC 
Closing this bug. Memory tests pass with flying colors, but it seems RH7+samba and FreeBSD+nfs on the same hardware both panicked in a similar 
manner. I now suspect it's a hardware issue, possibly the IDE chipset on this motherboard.
