Look in the IO ARS, under PDC_PIM() for info on decoding this stuff.
I'll decode a couple of key words, but I have to run to a meeting.

This should be the address of the instruction that caused the HPMC.  Use adb
against the kernel to see what this instruction is.  Then you'll probably
need to use the contents of the general registers above to figure out what
was going on:
> IIA Space                    = 0x0000000000000000
> IIA Offset                   = 0x0000000000010188

Bus check:

> CPU State                    = 0x9e000004

Read timeout:

> Assists Check                = 0x00000000

> Path Info                    = 0x00000000

Someone needs to look at an address map to see what address was being accessed:
> System Responder Address     = 0x000000fffff80810

cpu 0 is the requestor:
> System Requestor Address     = 0x000000fffffa0000



Off to the meeting...
