Hmm, I met a similar problem, on i386 2.6.29. The more interesting thing is that the normal boot is fine but a kexec boot will have this BUG_ON (about 50% chance), even 'irqpoll' doesn't help... My guess is that maybe some driver failed to request_irq during kexec boot, but I can't figure out which driver it is... Note, vector number is 0x79. -- Live like a child, think like the god.
