Machine check on Alpha

Machine check on Alpha

[Måns Rullgård]

My Alpha SX164 suddenly printed this on the console:

CIA machine check: vector=0x670 pc=0xfffffc0000351b78 code=0x98
machine check type: processor detected hard error
Kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing

Does anyone know what this particular machine check means?

A little while earlier, this oops appeared.  I didn't have time to
run ksymoops.
