kernel memory fault

My alpha just crashed. When I look at the vmcore with dbx -k,
it appears to be dying at the hands of ClearCase. (This has
happened before).

uerf gives this:

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

EVENT CLASS ERROR EVENT
OS EVENT TYPE 302. PANIC
SEQUENCE NUMBER 1.
OPERATING SYSTEM DEC OSF/1
OCCURRED/LOGGED ON Tue Feb 4 11:12:32 1997
OCCURRED ON SYSTEM aragorn
SYSTEM ID x00020009 CPU TYPE: DEC 2100
SYSTYPE x00000000
MESSAGE panic (cpu 0): kernel memory
fault

Q: Is this a hardware memory error or a problem with kernel data
   structures getting munged. (Output from dbx -k below)

Thanks. Will summarize.
