https://bugzilla.kernel.org/show_bug.cgi?id=203947 --- Comment #10 from Zorro Lang (zlang@xxxxxxxxxx) --- (In reply to Darrick J. Wong from comment #9) > Zorro, > > If you get a chance, can you try this debugging patch, please? Sure, I'll give it a try. With this bug together ... they both triggered by g/475. You really write a nice case :) Both these two bugs are too hard to reproduce, so I only can try my best to test it, but I can't 100% verify they're fixed even if all test pass, I'll try to approach 99% :-P BTW, if this's a separate bug, I'd like to report a new bug to track it, to avoid confusion.
