Probably solvable by adding unknown card ID to pci sources, but don't know where to modify the code to try that. hdac1@pci0:0:27:0: class=0x040300 card=0x83571043 chip=0x3a3e8086 rev=0x00 hdr=0x00 vendor = 'Intel Corporation' device = 'Microsoft UAA Bus Driver for High Definition Audio (Microsoft UAA Bus Driver for High Definition Audio)' class = multimedia subclass = HDA >How-To-Repeat: Fails on every reboot for this particular hardware. >Fix: If someone could tell me where in the kernel sources to look for the card ID type, would be willing to give it a shot. >Release-Note: >Audit-Trail: >Unformatted:
