@oded, thanks for the message! Maybe it's a different bug, however I think that the bug is still very close. If you look at the original poster's dmesg output, you see that the freezes (reported by the "hang" message) also occur multiple times. The only difference is that the frequency is about every 2 seconds, which makes the user feel it completely freeze all the time.
In my case it was a bit less frequent, but maybe that's just because I was putting less strain on the GPU. I will open a new ticket, as you suggested -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1861395 Title: system hang: i915 Resetting rcs0 for hang on rcs0 Status in Linux: Fix Released Status in linux package in Ubuntu: Fix Released Status in linux source package in Eoan: Invalid Status in linux source package in Focal: Fix Released Bug description: System hangs, unknown cause, When this happens, the mouse pointer still moves, but I can't do anything else with the keys or clicking in the UI.
