SubjectRegressions: MSI vs HDA-Intel
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

[ 1.252677] hda_codec: ALC888: BIOS auto-probing.
[ 1.259226] HDA Intel 0000:01:05.2: PCI INT B -> GSI 19 (level,
low) -> IRQ 19
[ 1.260293] HDA Intel 0000:01:05.2: irq 27 for MSI/MSI-X
[ 1.314712] input: GenPS/2 Genius Mouse as

polling mode: last cmd=0x000f0000
[ 5.332508] hda-intel: No response from codec, disabling MSI: last
[ 6.342508] hda-intel: Codec #0 probe error; disabling it...
[ 7.392508] hda_intel: azx_get_response timeout, switching to
single_cmd mode: last cmd=0x000f0000
[ 7.430464] ALSA device list:
[ 7.431549] #0: HDA ATI SB at 0xfe7f4000 irq 16
[ 7.432656] #1: HDA ATI HDMI at 0xfe9e8000 irq 27

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

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

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
