Description florz 2010-02-17 00:17:38 UTC
Sound playback starts stuttering as soon as I load the speedstep-smi driver
on my T20 thinkpad (with T22 BIOS), without even having changed the frequency.
Frequency switching otherwise seems to work fine. I can get rid of the
stuttering by causing 100 % CPU load - but that's somewhat counterproductive
given that I wanted to reduce power consumption ... :-)

It's great that kernel bugzilla is back.

can you please verify if the problem still exists in the latest upstream
kernel?
Comment 2 florz 2012-01-18 15:43:04 UTC
I will as soon as I get around to upgrading the kernel, which likely won't be too soon, though--expect a month or two of latency ...
Comment 3 Zhang Rui 2012-01-19 02:08:28 UTC
Get it.
As we will close the bug if we don't get response from the bug reporter for a month, how about this? I'll close it for now, and you can reopen it once you get chance to upgrade the kernel.
Comment 4 florz 2012-01-19 22:29:42 UTC
Reset it to whatever state it managed to survive the last two years in? =:-)

I've got no clue what makes sense as far as bugzilla is concerned, so do whatever you think is appropriate.
