Re: Unexpected HPMC FLT 20B4

Looks like a High Priority Machine Check on a processor. If under support, time to call in. If not try a reboot, but I think you are in deep.

Sorry I could not be more helpful.

Best regards,

Robert -
Also to a search on HPMC/TOC and you will find other helpful information to identify the fault. i.e.

According to these you probably have some serious processor issues:

FLT CBF0 - HPMC handling initiated
FLT CBFB - Branching to the OS HPMC handler
FLT 20B4 - Chassis code 2xyy (x=Processor Memory bus slot number) - Cache errors.
FLT 5008, 5408 and 5508 - Chassis code 5xyz (x=Processor Memory bus slot number y=System Bus Number) - Bus Transactions errors

If this is under hardware support, it's time to call HP.
