[alsa-devel] PATCH: Fix snd-hda-intel boot hang on ASUS A8N-VM
This patch fixes a regression in 2.6.33.x. Was working in 2.6.32.x.
Symptom: Hang on boot at "HDA Intel". Boots only if on-board sound is disabled or if "snd-hda-intel.enable_msi=0" is appended to boot parameters.
Machine: ASUS A8N-VM with Athlon-X2 processor.
Relevant output from lspci -nn:
00:10.1 Audio device [0403]: nVidia Corporation MCP51 High Definition Audio [10de:026c] (rev a2)

Proposed patch (which has been confirmed to allow boot, with sound active):

Thanks for the patch. The issue was already fixed in a different way, namely, disable MSI for all Nvidia controller chips. The fix will be included in the next pull request and stable kernel.

Can you provide a bit more information? I've the same issue at hand, on an Acer Aspire 9300 notebook, also with nvidia chipset. So far I disabled snd-hda-intel module loading, but it'd be nice to actually have sound working on this machine, as well as to test the patch... ;)
Thanks!

Take a look at:
commit 80c43ed724797627d8f86855248c497a6161a214 Author: Takashi Iwai tiwai@suse.de Date: Mon Mar 15 15:51:53 2010 +0100
ALSA: hda - Disable MSI for Nvidia controller
It's marked to Cc to stable, so the patch will be applied later to 2.6.33.x kernel, too.
