Subject: snd_hda_intel 2.6.24-rc2 bug: interrupts don't always work on Lenovo X60s
Date: Thu, 08 Nov 2007 14:48:32 -0800	[thread overview]
Message-ID: <ada1wb05p6n.fsf@cisco.com> (raw)

With 2.6.24-rc2 on my Lenovo X60s, I sometimes get:

    hda_intel: No response from codec, disabling MSI: last cmd=0x002f0d00
    hda_intel: azx_get_response timeout, switching to polling mode: last cmd=0x002f0d00

when loading snd_hda_intel.  Sound still works but interrupts aren't generated.

I tried bisecting but I haven't gotten good info yet because it seems
that this is not completely reproducible -- sometimes when I load the
module, it works fine, and other times I get the message.

I think this is a regression, since I don't recall ever seeing the
message with 2.6.22 or so.

Any idea on how to help debug this?

Thanks,
  Roland
