@David - as far as I know, before reporting kernel issues, Ubuntu users are expected to try a repro with a mainline kernel. I've read (some of) the discussion in the Freedesktop bug report where people have proposed that various patches have possibly solved the problem, so I hit the mainline PPA and got the newest 5.4 :-). And it looked promising for a while.
Currently running 5.4.0-15-generic #18-Ubuntu from focal-proposed, and so far so good. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861395 Title: system hang: i915 Resetting rcs0 for hang on rcs0 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1861395/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
