I'm seeing a lot of these on my 486/66 box.  It's possible that there
are still bugs in the VM system that didn't get squashed that affect
certain hardware.  It *appears* to happen on my box when doing heavy DMA
which happens during heavy duty compiles, or backups.  (Basically, when
the machine has non-stop disk activity for > 20 minutes)

I've been thinking my problem was bad memory, but it's possible that
it's a generic FreeBSD 1.1.5 problem.  My advice is to try installing
2.0 and see if the problem goes away.  Alot of post 1.1.5 fixes made
it into 2.0, so it's possible that the bug was squashed.

Alot of these problems should go away in 2.1 when the mergeg VM/buffer
cache is implemented.  Many of the coherency problems are supposed to be
fixed according to David Greenman and John Dyson.
