Comment (by korli):
The intr handler rt2560_intr() and rt2661_intr() have in common that they
don't check if the interrupt is theirs before proceeding. This can
certainly pose problems when the interrupt line is shared, which seems the
case (USB, SATA, HDMI Audio).
As to why it doesn't pose problem in FreeBSD, they probably only use MSI
and don't share interrupts anymore. Just a guess.
