Hi Ron,
Fighted the same problem on mine. It seems to be a problem of interrupts
dynamic routing on those old good opterons.
I fixed it by sticking all interrupts to processor 0 (cpuset -l 0 -x
..). Since then, it works without any trouble.

I am using a sunfire x4500 (thumper) with a pair of dual-core opteron 290
processors, running 10.1-RELEASE to serve up zfs filesystems via nfs and samba.
The system reboots periodically when under load. I cannot find anything in any
of the system logs that would account for why it rebooted, it just goes away
for a while and comes back in a few minutes.
Out of desperation, I tried disabling all but one of the processors.
(hint.lapic.x.disabled=1 where x == 1, 2 and 3). Oddly enough the system
doesn't reboot anymore.
Is there any known issues about SMP not working on a sunfire x4500? I have
searched the mail archives and haven't found anything useful.
thanks in advance for any help or suggestions.
ron.
