Description Dimitar Kosev 2006-04-09 07:34:43 UTC 
Most recent kernel where this bug did not occur: none
Distribution: Gentoo
Hardware Environment: Pentium D 805, VIA P4M800CE + VT8251 (Asus P5VDC-MX)
Software Environment:
Problem Description:

I have this board and this "VIA Technologies, Inc. VIA High Definition Audio
Controller" is I think uncorrectly recognised and this makes the two PCI slots
unusable (anything pluged in this slots wont work, lspci wont show it), couse
kernel thinks there is this VIA HDA, but it's not. I compiled kernel with "PCI
access mode"=BIOS and now they works. 

Here my lspci with "PCI Access mode = ANY"

This fake "02:01.0 Audio device: VIA Technologies, Inc. VIA High Definition
Audio Controller" seem to represend 05:08.0 and 05:09.0. Also from alsa-project
advise me to bug this here because the onboard sound is not workind and they
think it is some "ACPI IRQ routing bug"

Steps to reproduce: Compile any kernel with "PCI Access mode = ANY" and use this
board. Same on x86 and x86_64
