Description drago01 2007-12-09 11:59:52 UTC
Description of problem:
The snd-hda-intel driver switches to polling mode some time after boot which
causes it to waste power. The card still work fine in this case. 
There is an upstream (2 liner) patch that fixes this issue. It won't get into
stable because the alsa version in 2.6.23 is not affected but we are shipping an
updated version (1.0.15). 
Can we get the patch in question (http://lkml.org/lkml/2007/11/23/17) into the
kernel rpm for f8? It also has a positive side effect too: it speeds up
suspend/resume. 
And there are no known negative side effects.
