Mike, I noticed your work trying to debug the issue, and you finally
succeeded to get a usable backtrace which is good. I just weren't
able to get to you earlier.
Can you also check whenever hda emulated device also shows this issue?
Vassili, can you take a look please - the prob appears to be somehow
sound-related..
Thank you!
