That's an HPMC (High Priority Machine Check).
A bit more info is available from the firmware: PIM dump.
See the "howto report kernel bugs":

The PIM dump should help you track down where it's dying in the code.

I'd also suggest posting the PIM dump to the parisc-linux mailing list
instead of debian-hppa if you need help decoding it.
