may i suggest, based on your symptom (ie southern islands gpu lockup in tf2; you're fortunate that a gpu reset is successful unlike me), that you look at bug #1652486.
after rebuilding mesa with the upstream patch applied (see patch in aforementioned bug report) and installing the resulting packages (specifically libgl1-mesa-dri:i386 as tf2 is i386 even on amd64, but also dependencies and associated packages) tf2 no longer prompts a gpu lockup (even after hours of game play, where it use to occur in under 10 minutes). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1643362 Title: GPU lockup with radeon driver and ATI R9 280X card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1643362/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
