I hadn't
started this DEC Alpha 3000-300 since last
summer, and booted it up so I could load the new PAK's
the other day.
The result was that it completes almost the entire
OpenVMS startup, but then crashes with the following:
%SET-I-INTSET, login interactive limit = 64, current
interactive value = 0
**** OpenVMS Alpha Operating System V8.4 - BUGCHECK ****

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.
