It could be the snd_hda_power_up_pm() call, but that would seem > unlikely, so most probably something goes wrong in silent_stream_enable(). Say no more! One kernel compilation that might yield some concrete results I can bare (since I'm currently with very weak hardware and compiling the kernel takes over an hour at best, and not a few minutes or even seconds like probably does in your development machines) I'll do it tomorrow since it's late here, or if Takashi can spoil me a bit more with a patched kernel from OBS that would be awesome *wink* *wink* Also speaking of OBS is it open to everyone or just for suse developers? I can probably learn to use it and patch test kernels myself, (if I can use it) so I don't waste Takashi's time with boring, one time kernel builds for testing.
