Created attachment 62466 [details] dmesg before the incident After an update to Kernel 3.4 (via openSUSE Tumbleweed), my GPU acts weird after a couple of minutes, this is accompanied by lots of "MMIO read or write has been dropped" reports in dmesg and a "Detected a hung GPU, disabling acceleration" in Xorg.0.log. This results in a loss of graphic acceleration as well as strange graphical artifacts: fonts are not rendered properly, the xterm cursor vanished, colored and highlighted text in xterm is not readable, mplayer cannot play videos any more, whole sections in most windows are not updated properly and get garbled until I e.g. minimize and reactivate it. System environment: -- chipset: H67 -- system architecture: 64-bit -- xf86-video-intel: 2.16 -- xserver: 1.10.4 -- mesa: 7.11 -- libdrm: 2.4.26 -- kernel: 3.4.0 -- Linux distribution: openSUSE Tumbleweed -- Machine or mobo model: ASrock H67M -- Display connector: HDMI Reproducing steps: Boot system, work, after a few minutes of perfect operation (sometimes up to half an hour or longer) the "GPU hangs". Additional info: dmesg with drm.debug=0x06 (two files, one before and one after the incident, as the error message quickly fill the kernel buffer) lspci, i915_error_state, Xorg.0.log, output of hwinfo (a SuSE tool?) for graphics adapter

Can you please test with i915.i915_enable_rc6=0 on the kernel commandline?
(In reply to comment #7) > Can you please test with i915.i915_enable_rc6=0 on the kernel commandline? I have that set for some days now and the problem so far has not happened again.
Can confirm this, also with openSUSE, only difference in my configuraiton seems to be kernel 3.4.3 and DisplayPort: System environment: -- chipset: H67 -- system architecture: 64-bit -- xf86-video-intel: ? -- xserver: ? (openSUSE package version: 7.6_1.10.4) -- mesa: 7.11 -- libdrm: 2.4.26 -- kernel: 3.4.3 -- Linux distribution: openSUSE Tumbleweed -- Machine or mobo model: ASrock H67M -- Display connector: DisplayPort Any need for my dmesg or i915_error_state? My dmesg is full of these sections: [ 318.958892] ------------[ cut here ]------------ [ 318.958920] WARNING: at /home/abuild/rpmbuild/BUILD/kernel-desktop-3.4.3/linux-3.4/drivers/gpu/drm/i915/i915_drv.c:398 gen6_gt_check_fifodbg.isra.5+0x2e/0x40 [i915]() [ 318.958925] Hardware name: To Be Filled By O.E.M.
