Comment 7 for bug 2061091

And this call trace looks is related to current issue, I guess snd_power_ref_and_wait was waiting for snd_card_disconnect which wakes up power_sleep at the end of the code, but snd_card_disconnect -> snd_device_disconnect_all -> snd_pcm_dev_disconnect was blocked for some reason.
