This is probably the same as bug #1871867, can you confirm? I've had this bug ever since upgrading to Ubuntu 18.10 (i.e. the Linux 5.3 kernel series). However before the 5.3.0-46-generic update (when I was on 5.3.0-45-generic and earlier versions), I had this issue (freezes of around ~10s) only a few times per day. After the 5.3.0-46-generic update, this bug happened several times per hour, sometimes repeating in the timeframe of minutes. Though I only rarely get the "GPU HANG: ecode 9:0:0x00000000, hang on rcs0" message prior to the "Resetting rcs0 for hang on rcs0" message, for what's it worth.
To put this into numbers, from April 4 to April 9 (daily usage), I only got 6 freezes, whereas since the update to 5.3.0-46-generic (which I performed on April 10), I've got 122 hangs already. This makes using the whole system really annoying. There are some interesting discussions about this bug on https://bbs.archlinux.org/viewtopic.php?id=250765, though note that there seem to be multiple bugs and it got worse with later kernel versions, including unrecoverable freezes on kernel 5.4 (which were reported in Ubuntu as bug #1861395). I've reverted to Linux 4.19 LTS mainline kernel from https://kernel.ubuntu.com/~kernel-ppa/mainline/ for now, and haven't had any more freezes yet. -- 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
