MSR shows it died in 32-bit real mode: i.e. in the firmware.

I've seen this sporadically, I've assumed it was the off-kilter firmware
on the box I have access to.  But since you're seeing it...

John Rose, the maintainer of librtas (the user space lib that does
the memory mapping) tells me that even if corrupt values are passed to
RTAS, the firmware should not crash.
