Sorry for writing again, but no one answered me. Of course, I checked my memory again and ensured that it was fine. I even changed three motherboards, but this error appears once a week. Every time the common phrase is "BUG: Bad page state in process" but the process can be different. kcompactd, kswapd, kworker, btrfs-transacti I don’t know if this will help, but usually this happens when I run the “docker pull” command and a huge container is being updated. -- Best Regards, Mike Gavrilov.
