The only significant change last time was enabling MSI by default. But I don't think it should lead to such errors. I have tried even operation completely without interrupts working and there is not such errors. Can you send me complete verbose dmesg with the problem and `pciconf -lvc` output? Also you may try to disable MSI by setting 'hint.hdac.0.msi=0' hint. -- Alexander Motin
