I have a repeatable crash in the Advansys SCSI driver adw.
Under intensive disk use (an UW Western Digital 9.1 gig)
the following error happens and the system falls into
the debugger (this particular time I was copying some
directories with pax):

kernel: page fault trap, code=0
stopped at AdwISR+0x12c: movl %eax, 0x34(%esi)

The debugger trace follows.  The (...) is where my hand
was cramping up from copying all this down.  There's no
dump since typing 'continue' just gave the page fault trap
message above.  The disk is mounted with softdeps enabled.
If more info is needed, please let me know.  The kernel
version is 1.5 - I had the same error under 1.5L.
