>Description:
No attach to device - chip ID is known by hdac, but card ID is not:
pciconf yields:
none0@pci0:0:27:0: class=0x040300 card=0x82fe1043 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
none1@pci0:0:31:3: class=0x0c0500 card=0x82d41043 chip=0x3a308086 rev=0x00
hdr=0x00
vendor = 'Intel Corporation'
device = 'SMB controller (50011458)'
class = serial bus
subclass = SMBus
none2@pci0:1:0:1: class=0x040300 card=0x34fe1458 chip=0x0be910de rev=0xa1
hdr=0x00
vendor = 'NVIDIA Corporation'
class = multimedia
subclass = HDA
-----
Chipset is known for the none0@ entry, but card ID is unknown. 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.
