Created attachment 83919 [details] dmesg log containing several GPU lockups Upgrading xf86-video-ati to 7.2 has caused very frequent GPU lockups on my machine (one after the other), after a while even causing my machine to spontaneously reboot. I'm using a Radeon HD7850, on a fully-updated 64bit Arch Linux installation (Linux 3.10.5, Xserver 1.14.2). Attached is a dmesg from when the GPU locked-up but I managed to switch to a TTY console, after which my system didn't lock-up and I could collect the dmesg (but forgot Xorg.log). My xrandr configuration: Screen 0: minimum 320 x 200, current 2960 x 1050, maximum 16384 x 16384 DisplayPort-0 disconnected (normal left inverted right x axis y axis) DisplayPort-1 disconnected (normal left inverted right x axis y axis) HDMI-0 connected 1280x1024+0+20 (normal left inverted right x axis y axis) 340mm x 270mm 1280x1024 60.0*+ 75.0 1024x768 75.1 75.0 70.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 DVI-0 connected primary 1680x1050+1280+0 (normal left inverted right x axis y axis) 474mm x 296mm 1680x1050 59.9*+ 1280x1024 75.0 60.0 1280x960 60.0 1152x864 75.0 1024x768 75.1 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 72.8 75.0 66.7 60.0 720x400 70.1
Created attachment 83920 [details] xorg.log on a working configuration (using driver 7.1) Attached an xorg.log using 7.1 (because I forgot to save the one when booting using 7.2) to show I'm not using any special X configuration but relying on the autodetected one.
I am experiencing the same, also using Arch Linux, although with a Radeon 7750. I am using kde and just opening firefox seemed to cause the lockup along with the screens blanking. After reviewing the changelog, I noticed the enabling of glamor by default for the radeonsi driver, so tried changing the AccelMethod back to EXA. This caused the system to become stable again
There is no EXA support for SI and newer asics. glamor is required for acceleration.
Understood - my point being that if I tell it not to use Glamor (by passing the AccelMethod of EXA) then my system becomes stable again and doesn't suffer from things such as GPU lockup when opening firefox
Which version of Mesa are you using?
Latest stable release from the ArchLinux repositories, Mesa 9.1.6
