Hi,
I have a number of systems running NetBSD 1.1, on a board from TriEMS.
They use the AMD486DX4/100 with the write back cache.  We are seeing
spontaneous VM_FALTS.  All boards seem to do it sooner or later.  Some
systems may crash frequently and others, one or twice a month.

I wrote a simple script that runs about 40 instances of "find".  This will
crash almost any system within 1 to 5 minutes, but we can't seem
to figure out if we have a hardware or software problem, or a 
combination of both.  Anyone have any ideas what to check?

BTW, these boards seem to run just fine with OS/2 or Windows.

Mark
