The result was that it completes almost the entire

The disk is a SCSI2SD board with an 8 GB SD card. It had
been running just fine, until now.
Does this crash point to a hardware or software problem?
I think "Exception while above ASTDEL" refers to an
exception encountered
while processing an interrupt in kernel mode, probably in
device driver code.
I think this leans more in the direction of a sofware
problem while something
like "Machine check in kernel mode" would lean more in the
direction of a
hardware problem.
Well, most of my deeper experience in the driver level is
VAX and not Alpha, I think a memory exception is still a
machine check, and so trying to access a memory or device
location that does not exist/respond is still a machine
check at the very lowest level.
