	K6-III 350
	128 meg RAM
	Advansys ABP-940UW SCSI controller
	WD 9100 9.1 gig SCSI disk, all NetBSD, mounted with SOFTDEPS
System: NetBSD 1.5 (BSD) #0: Thu Dec  7 13:47:32 EST 2000 root@bsd:/usr/src/sys/arch/i386/compile/BSD

	Under intensive disk use, 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:
