Andrea, sorry to disappoint you, but I've definitely had this bug even in earlier 5.3 kernel versions (i.e. also on -45), just with a lower frequency. See my comment 24 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872001/comments/24) for details.
Interestingly contrary to others, I haven't had it happen once since I upgraded to your 5.3.0-48-generic kernel. I use the following command to check syslog for freezes: zgrep -ah 'Resetting rcs0 for hang on rcs0' /var/log/syslog* -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872001 Title: 5.3.0-46-generic - i915 - frequent GPU hangs / resets rcs0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872001/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
