Looks like interrupts are not delivered/processed correctly. I suspect
interrupt vector number was not determined correctly. It would be
interesting to look at firmware configuration (prtconf -pv) and complete
bootlog. Also DEBUG kernel might notify about 'spurious' interrupts and
has interrupt disgnostics so I'd use that one.
