Thanks for the narrowing it down. It looks like perhaps that patch was
ineffective at trying to keep us out of using IRQF_ONESHOT due to
irq_setup_forced_threading() re-enabling it. Does the problem go away if you
change the two calls to request_threaded_irq() in that commit to use
IRQF_NO_THREAD for the flag value in place of 0?
