Another "data point".  It was happening here as well on a Pentium 200/MMX.
The crash occurred, almost everytime, in a bcopy called from vm_fault
according to the kernel debugger (on the rare occassions I could still use
it).  Whenever I couldn't use the debugger, the Instruction pointer was
usually 08:ffffffff.  I stuck an old P-III 800MHz/PC133 machine in its
place and everything has worked flawlessly since.
