Hello,
The kernel of the upcoming Debian release and some recent kernels of Ubuntu seem to be suffering from HDA running at full force upon wakeup and producing a lot of heat (keeping the fan spinning loudly).
What do you mean "wakeup"? Which kernel are you using? Which codec and HD-audio controller chips? Please elaborate a bit more instead of a bug track URL. This will save lots of time for other people.
If it's really a CPU usage, try to run perf and check what is spinning around.
thanks,
Takashi
The bug tracking can be found here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/877560is there anything known about this problem? What the root of the problem is? How to solve it? Are there patches? Are there kernels that have fixed the problem? Are there workarounds?
The problem seems to be impacting quite a few users. *t _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
