How about

	http://www.freebsd.org/cgi/query-pr.cgi?pr=17122

I remember hitting this on a couple of 3.4 boxes and had to turn off
softupdates (those were production machines). It was not even a SMP machine.
The PR is still open, and I guess still present in 4.0 (I vaguely remember
hitting it on a 4.0 box as well, where I forgot to turn off softupdates). The
PR is talking about the machine crashing every 1-3 days, mine was crashing
more like twice per month. Since that time I don't turn on softupdates on any
of my production boxes.

Unfortunetlly I cannot contribute anything to the PR itself, as:
1. All the machines that exhibited the problem where production machines.
2. My home work box (running 5.0-CURRENT) doesn't exhibit the problem,
   probably because it is being turned off every day and there is no real load
   on the machine.
3. When the machines crashed, I didn't have a debug kernel running so the
   crashdumps would be mostly useless.
