Comment 13 for bug 1901563

I'm actually going to close the upstream issue - I'm still not clear on the root cause - it is a slab/kmem cache issue, but I don't which subsystem is responsible for it. It might get visible on opening various kernel debug options, but it requires to recompile and also slows down the system dramatically, unfortunately I don't have the time for that :( Especially as the issue went away after installing the linux-5.9.3 kernel. I guess switching to wayland just avoid the trigger, but the 5.8 kernel seems to have a bad bug.
