Hi, all.

I am the administrator of a (somewhat :-) old alpha (DEC 2000 AXP 300),
running DU 4.0d with patch kit 2 applied.

A few minutes ago it paniced. uerf says:

----- EVENT INFORMATION -----

EVENT CLASS ERROR EVENT
OS EVENT TYPE 302. PANIC
SEQUENCE NUMBER 1.
OPERATING SYSTEM DEC OSF/1

MESSAGE panic (cpu 0): Unaligned kernel space
                                         _access from kernel mode

and the kern syslog says:

Oct 14 11:57:09 haddock vmunix: Unaligned kernel access va=0xfffffc0002e7a487
   pc=0xfffffc000037a0b4 ra=0xfffffc000037a414 inst=0xffffffff

Oct 14 11:57:09 haddock vmunix: DUMP.prom: dev SCSI 1 6 0 0 0 0 JENS-IO, block 0

(the two first lines are splitted for readability)

Does anyone know any possible cause? The machine hadn't paniced since the
DU 2.0 days.

Thanks in advance,

        Pedro.
