These lockups and SCSI troubles seem interrupt related - your image is
showing the ESP as having done a successful reconnect after a disconnect
in the previous interrupt, and from the hw reread it seems a BUS SERVICE
interrupt is showing (which is apparently not picked up, hence the
aborted command). HW reread should never have an interrupt showing.
This happens because there's a bug in the handling of VIA interrupts
which may cause ESP SCSI interrupts to be missed. Finn and me debugged
this back in september 2004.
You probably need the following patch from Finn Thain:
[PATCH] m68k mac VIA2 fixes and cleanups
It must have slipped through. Finn, do you want me to commit this patch
to the Linux/m68k CVS repository?
