The kernel boots only with pci=routeirq, no IRQ get disabled but the
sound driver does not work.

http://olivn.trollprod.org/19-rc6/19-rc6-yinghai1-routeirq.irq
In order to get reproductible result, I halt the system and remove the
power cord for 30 seconds.But once, I just reboot and get that strange
result
IRQ 22 is disabled but snd_hda_intel seems to get a MSI interrupt! (It
cannot be reproduced)
