I'm afraid I've got to add a 'me too'... I hadn't been recording it,
metoo
I've not been able to get a crash dump. dmesg is always reset each
time. Unfortunately the machine is remote and unattended. I had
though of hooking up a serial console that I could monitor from one of
the machines next to it, but the machine doesn't have any serial
ports....
So, we have a machine that silently reboots with no way of knowing
what is causing it...
I get lockup almost every time the kernel puffs this out:

*LOCKUP*
nfsd(s) getting killed from a 1.1.5.1 server seems to be a way to exhibit
this. I haven't gotten any dumps since last -current upgrade, the systems
always lock up or panic but leave no dump. Systems without lots of nfs
mounts and access seem much more stable. 2.2-current kernel is from
mid-november.
Other fancy things, in addition to various SCSI problems every now and
then:

These don't seem to be (directly) harmful, though, as the system usually
does not crash right after these.
