https://bugzilla.kernel.org/show_bug.cgi?id=201847 --- Comment #1 from Marc B. (kernel.org@xxxxxxxxxxxx) --- It would be soooo cool if anyone would actually read this bug report and maybe try to fix it. I will assist in testing patches until this is resolved. And: I am willing to offer $100 for fixing this annoying bug! Keeps freezing my 4.19.39 kernel out of nowhere. Some things I would like to get into discussion: a) - it might have something to do with memory pressure _and_ b) - high CPU load _or_ - high number of context switches. For the latter I'm not sure. The bug actually always occurs when I ie. compile two kernels at -j24 and habe some other work besides this, say a YT video. The bug is, however, definitely triggered by a graphics event, ie. resizing/creating a window, scrolling a Web page or watching a video.
