I didn't try to make sure if it's a regression or not. Due to 1. This bug is very hard to be reproduced. 2. The reproducer(generic/475) might easily to trigger some other issues on old kernel. Any way, I'll give it a try on v4.19, but I can't promise that I can find out if it's a regression:) -- You are receiving this mail because: You are watching the assignee of the bug.
