commit: d7dab4dbbb2d1b0c903378d6bade2e4ae161804e From: Takashi Iwai <[email protected]> Date: Tue, 8 Jan 2013 13:51:30 +0100 Subject: ALSA: hda - Disable runtime D3 for Intel CPT & co
We've got a few bug reports that the runtime D3 results in the dead HD-audio controller. It seems that the problem is in a deeper level than the sound driver itself, so as a temporal solution, disable the feature for these controllers again.
