This is not really helpful because that's in the middle of the queue and
that code is gone at the very end. Yes, it's unfortunate that this
breaks bisection.

Can you please test:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86/irq

which contains fixes and if it still crashes provide the dmesg of it.

Thanks,
