Apparent NFS related crashs on PowerEdge 2900 running SLES 10

[Peter Serwe]

I've only seen a crash on an NFS server once.  In my particular case, I 
have no real diagnostics to
show for it, just that it was a CentOS 4.4 x86_64 server, on a PowerEdge 
2900, and I got an actual
kernel panic, requiring a reboot.  I found nothing in the logs related 
to it.
