    general protection fault: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC
    Call Trace:
     [<ffffffffa0159bd1>] ? kvm_set_irq+0xdd/0x24b [kvm]
     [<ffffffff8106ea8b>] ? trace_hardirqs_off_caller+0x1f/0x10e

    RIP  [<ffffffffa0159c72>] kvm_set_irq+0x17e/0x24b [kvm]
    This bug is triggered when guest is shutdown, is because we freed
    irq_routing before pit thread stopped
