Description Simone Piccinini 2004-08-31 01:02:23 UTC

when i move bus speed (in bios) from 133 to 149, alsa doesn't work anymore.
/proc/asound/cards shows no soundcards while lspci still recognize the card:
0000:00:1f.5 Multimedia audio controller: Intel Corp. 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 02)
at freqs >=150 lspci doesn't show it anymore.
could it be an hardware problem? or it is a kernel related issue?
could someone with my hw test it?

Reproducible: Always
Steps to Reproduce:
1.set bus freqs in bios >=149
2.
3.

Actual Results:  
first alsa then pci doesn't recognize the card anymore. 

Expected Results:  
alsa works

we generally do not address bugs with overclocked hardware.

Comment 2 Simone Piccinini 2004-08-31 09:28:49 UTC

no problem, feel free to mark this bug as invalid.
i am not an overclocker so it's not a troube of mine.
it was more a curiosity to understand why it doesn't work.
i've tried to find out but i haven't the necessary knowledge to look at pci and alsa internals.
sorry again for my eng.

Yes, we won't address this if its working fine at the standard clock speed. If you are bothered by this, I'd suggest that you attempt to reproduce it on plain development-sources and file a bug at http://bugzilla.kernel.org - but you may well be asked to stop overclocking.
