Bad day today,
Kernel compiled with the first parch irq_mcp55.diff
and with the disable_msi option removed.

Disabling IRQ #21
ALSA sound/pci/hda/hda_intel.c:543: hda_intel: No response from codec,
disabling MSI...
So kernl assign irq 21 to sata2, and later share irq 21 with audio.
But audio get MSI, and at that time, it may do sth bad to irq21 that it
is still shared with SATA2.
