I looked at dmesg, nothing out of the ordinary there. Unfortunately also no hints why the pipe is somehow off when we think it's on. Can you please test the below patch and grab a new dmesg?
Attached.
Also it might be time to start bisecting this if you can readily reproduce it.
Yes, I can reproduce it just by switching to the text console. Sometimes it is the first attempt already but sometimes it takes several attempts. I will try to go back to 4.0 and bisect it then.
