Sorry, I've been too busy and overlooked this update. Since the issue is reproduced in 4.11.x, could you report to upstream, e.g. bugzilla.kernel.org? The symptom appears to be a communication error and the stall after that, so it doesn't look like a generic problem I can check. Feel free to put me (tiwai@suse.de) to Cc when you open the bug report there for any assistance for openSUSE. Thanks.
