After a kernel bisect, it was found that reverting the following commit resolved this bug: commit 3822b5c2fc62e3de8a0f33806ff279fb7df92432 Author: Rainer Weikusat Date: Wed Dec 16 20:09:25 2015 +0000 af_unix: Revert 'lock_interruptible' in stream receive code The regression was introduced as of v4.4-rc6. I was hoping to get your feedback, since you are the patch author. Do you think gathering any additional data will help diagnose this issue, or would it be best to submit a revert request?
