System: NetBSD l.ox.ottawa.on.ca 1.1 NetBSD 1.1 (BUD) #0
During intensive disk activity, system crashes with (transcribed)
vm_fault(0xf8759000,0,1,0) -> 1
kernel: page fault trap, code=0
Stopped at ffs_sync+0x1a: cmpb $0,0xd0(%eax)
This hard disk and AHA controller was in a 386/33 before. The
system got dupped by putting an IDE controller and drive into the
386 and dump/restore'ing the SCSI drive. The SCSI drive was then
moved to a 486DX/2-50. I have turned all the caches off in hope of getting
something to stay up long enough to copy previously sup'ed sources
(from my NetBSD/sun3 system) to this machine. The 386, which is
bud.sandelman.ocunix.on.ca is alive and well with the same kernel,
and ran fine for months with that drive/controller. It is an AMI
bios (both of them, but different years).
I'm happy to try a 1.1B (-current) kernel, only the system doesn't
stay up long enough to compile one. I could build one on my 386, but
it is pathetically slow... (Perry, got one you can build me? I prefer
we0 at 0x300,IRQ 10)
P.S: 'call 0' results in a sync on NetBSD/sun3, and of course there
is "machine halt" and "machine reboot" instead of the reset button.
Is there a nicer way to get out of DDB?
Heavy disk activity, e.g. compiling kernel.
