Description Kaare Fiedler Christiansen 2007-08-03 12:52:33 UTC 
Description of problem:

After upgrading to the 2.6.22.1-41 from 2.6.22.1-33 an IRQ conflict is
introduced, disabling both my wireless card and my audio card. The result is
especially bad for audio, since any program that attempts to emit audio freezes.

Version-Release number of selected component (if applicable):

2.6.22.1-41.fc7

How reproducible:

Always

Steps to Reproduce:
1. Boot machine
  
Actual results:

IRQ is disabled, see attached output of dmesg.

Expected results:

In 2.6.22.1-33.fc7 both wireless and audio worked

Comment 3 John W. Linville 2007-08-03 13:51:39 UTC 
Hmmm...did you try booting w/ the "irqpoll" kernel command line option?
Comment 4 Kaare Fiedler Christiansen 2007-08-03 16:01:09 UTC 
I did, exactly same result (including the suggestion to try to boot with irqpoll...)
Comment 5 Kaare Fiedler Christiansen 2007-08-17 14:17:03 UTC 
I just upgraded to the latest kernel in updates-testing, 2.6.22.2-57.fc7, and
that fixes the problem.

Will this kernel reach updates? In that case I consider the problem fixed.
Comment 6 Kaare Fiedler Christiansen 2007-08-25 20:37:19 UTC 
Bug is fixed in new kernel from updates

2.6.22.4-65.fc7
