I have two systems that use the alsa hda-intel driver, both show regressions in relation to MSI.
System 1: Athlon(tm) X2 BE-2400 with an AMD RS690/SB600 chipset 00:14.2 Audio device [0403]: ATI Technologies Inc SBx00 Azalia (Intel HDA) [1002:4383] (Mainboard is a MSI MS-7368)
After upgrading from 2.6.31 to 2.6.33 I get a delay during bootup: [ 1.155925] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 1.159143] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input2 [ 1.232595] firewire_core: created device fw0: GUID 00dc10000129c48f, S400 [ 1.252677] hda_codec: ALC888: BIOS auto-probing.

2.6.34-rc2 does not boot on this system, something related to the new bootmem allocator, so I can't say if this might already be fixed for 2.6.34.
Should the system be blacklisted like the two Asus Athlon X2 boards, or is this some other bug?
System 2: Opteron(tm) 2218 with an nVidia MCP55 chipset 00:06.1 Audio device [0403]: nVidia Corporation MCP55 High Definition Audio [10de:0371] (rev a2) (Mainboard is an ASUS KFN5-D SLI)
Commit 80c43ed724797627d8f86855248c497a6161a214 disabled MSI for this system, but the MSI mode was working fine for all 2.6.33 versions I used.
Should the generic blacklist disable MSI for all Athlon X2 instead of all nNvidia chipsets?
If you need more information, please ask, I will try to provide anything you need.
Thanks, Torsten
