Description Kaare Fiedler Christiansen 2007-08-03 08:52:33 EDT

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 09:51:39 EDT

Hmmm...did you try booting w/ the "irqpoll" kernel command line option?

Comment 4 Kaare Fiedler Christiansen 2007-08-03 12:01:09 EDT

I did, exactly same result (including the suggestion to try to boot with irqpoll...)

Comment 5 Kaare Fiedler Christiansen 2007-08-17 10:17:03 EDT

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 16:37:19 EDT

Bug is fixed in new kernel from updates

2.6.22.4-65.fc7
