Created attachment 135141 [details] dmesg 4.14.0-rc6-mainline Seems like this is fixed in mainline.

Kernel 4.14.12 brings the same problem for my (same) device. Up until 4.14.11 , things worked fine.

(In reply to Mahfuz from comment #5) > Kernel 4.14.12 brings the same problem for my (same) device. Up until > 4.14.11 , things worked fine. Could you try to bisect between 4.14.11 and 4.14.12?

First of all. Sorry about spam. This is mass update for our bugs. Sorry if you feel this annoying but with this trying to understand if bug still valid or not. If bug investigation still in progress, please ignore this and I apologize! If you think this is not anymore valid, please comment to the bug that can be closed.
