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

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)
