I tried to get a backtrace via SSH, but no luck. I can start the gdb session and attach to the Xorg process, but the moment the bug occurs (screen freeze), I can't send any signals through my SSH session either. A few times I had to do a hard-reset because Magic SysReq was not recognized anymore (REISUB sequence).
There were two things that changed when attaching a gdb session, aside from REISUB not working: 1. I got a few frames from the game (meaning, my ship spawned and everything went fine for ~3 seconds) 2. the kern.log file had a bunch of this inside of it: [ 745.250679] radeon 0000:02:00.0: GPU lockup (current fence id 0x000000000000f5a5 last fence id 0x000000000000f5b2 on ring 0) [ 745.749923] radeon 0000:02:00.0: ring 0 stalled for more than 89868msec [ 745.749932] radeon 0000:02:00.0: GPU lockup (current fence id 0x000000000000f5a5 last fence id 0x000000000000f5b2 on ring 0) [ 746.249238] radeon 0000:02:00.0: ring 0 stalled for more than 90368msec [ 746.249247] radeon 0000:02:00.0: GPU lockup (current fence id 0x000000000000f5a5 last fence id 0x000000000000f5b2 on ring 0) [ 746.748547] radeon 0000:02:00.0: ring 0 stalled for more than 90868msec [ 746.748556] radeon 0000:02:00.0: GPU lockup (current fence id 0x000000000000f5a5 last fence id 0x000000000000f5b2 on ring 0) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1438303 Title: Radeon driver freezes GPU (reproducible) Status in xserver-xorg-video-ati package in Ubuntu: New Bug description: Hi, System: lsb_release -rd Description: Ubuntu Vivid Vervet (development branch) Release: 15.04 Package: apt-cache policy xserver-xorg-video-radeon xserver-xorg-video-radeon: Installiert: 1:7.5.0-1ubuntu2 Installationskandidat: 1:7.5.0-1ubuntu2 Versionstabelle: *** 1:7.5.0-1ubuntu2 0 500 http://de.archive.ubuntu.com/ubuntu/ vivid/main amd64 Packages 100 /var/lib/dpkg/status GPU: Radeon HD 5870 I upraded from Ubuntu 14.10 to 15.04 (x64) three days ago. After the upgrade I was not able to play a specific game (Star Conflict) with the open-source radeon drivers. (It does work with fglrx, very low FPS, but it does work) The game did work on Ubuntu 14.10 hours before I upgraded, so a game bug or hardware bug can be excluded in my opinion. Steps to reproduce: 1. On a computer that uses the open-source radeon driver, start Star Conflict. 2. log-in and start a custom game against bots 3. start the match 4. wait until the countdown is completed and you are launched Expected result: I can fly around and shoot at those bots Reality check: X freezes, I get a garbled up screen for a second and then the image I had before. I can still move my mouse, but nothing reacts. I can change to tty1 and kill the X server/gdm and restart it but it just shows me the exact same image I saw before. Game logs are clean. dmesg/kern.log shows this [quote] [drm:r600_ib_test [radeon]] *ERROR* radeon: fence wait failed (-35). [drm:radeon_ib_ring_tests [radeon]] *ERROR* radeon: failed testing IB on GFX ring (-35). [/quote] I checked any log file I could find/think of, but kern.log is the only thing that shows anything. To get back to a working system I have to reboot.
