Patch "genirq: Add IRQF_RESUME_EARLY and resume such IRQs earlier" has been added to the 3.1-stable tree
...re_resume instead of dpm_resume_noirq. Under Xen we need to resume IRQs associated with IPIs early enough that the resched IPI is unmasked and we can therefore schedule ourselves out of the stop_machine where the suspend/resume takes place. This issue was introduced by 676dc3cf5bc3 "xen: Use IRQF_FORCE_RESUME". Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Cc: Rafael J.

[PATCH] irq: Exclude percpu IRQs from being fixed up
irq: Exclude percpu IRQs from being fixed up Xen spin unlock uses spurious ipi "lock_kicker_irq" to wake up blocked vCPUs waiting on that lock. This irq should always be disabled. However, when Dom0 is shuting down, function fixup_irqs is called which unmasks all irqs. Function unmask_irq effectively re-enables lock_kicker_irq and its irq handler is invoked which reports bug and crashes
