Regression: New kernel introduces irq conflict between wireless and audio
Last modified: 2007-11-30 17:12:12 EST
Description of problem:
After upgrading to the 18.104.22.168-41 from 22.214.171.124-33 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):
Steps to Reproduce:
1. Boot machine
IRQ is disabled, see attached output of dmesg.
In 126.96.36.199-33.fc7 both wireless and audio worked
Created attachment 160602 [details]
Ouput of dmesg
Created attachment 160607 [details]
dmesg output from 188.8.131.52-33 kernel
Hmmm...did you try booting w/ the "irqpoll" kernel command line option?
I did, exactly same result (including the suggestion to try to boot with irqpoll...)
I just upgraded to the latest kernel in updates-testing, 184.108.40.206-57.fc7, and
that fixes the problem.
Will this kernel reach updates? In that case I consider the problem fixed.
Bug is fixed in new kernel from updates
