Chris, I seem to be experiencing this bug in Linux 4.7rc3 on an x220 ThinkPad with Intel HD 3000 chipset. I was getting random full system freeze, non responsive over network.
The main messages before the crash were: Jun 23 19:11:18 athena kernel: [drm:fw_domains_get [i915]] *ERROR* render: timed out waiting for forcewake ack request. Jun 23 19:11:18 athena kernel: [drm:__gen6_gt_wait_for_thread_c0.isra.7 [i915]] *ERROR* GT thread status wait timed out. The original crash I haven't been able to reproduce easily but I CAN reproduce every time a full system lockup running the following intel- gpu-tools tests (I have not even close to run all the tests though) [**This may or may not be related to the original crash**] gem_sync, subtest: bsd2-hang drv_hangman, subtest: error-state-capture-bit I do not know if these tests are helpful or related (maybe some are known to fail? not sure). I have drm debugging turned on for when I ran those tests. (drm.debug=0x1e log_buf_len=1M) I can post logs of the hangs associated with the two tests/subtests and run any other tests if you desire (with kernel drm debug on), I will wait for the issue to reappear with the drm debug on before posting that log though. By the number of similar bugs you may already have the CALL TRACE and non-debug level logs. I know how to patch and am able to compile kernels to test. The bug effects me maybe once every 1 or 2 days. I use XOrg with Glamor. I have been seeing these crashes since 4.6 (maybe 4.5 or earlier not sure). I know how to apply patches and am able to compile drm-next or any patches you have to see if this issue can be isolated. Thanks, sorry for the long response. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1041790 Title: [snb] GPU lockup IPEHR: 0x0b160001 IPEHR: 0x0b140001, workaround i915.semaphores=0 Status in xf86-video-intel: Won't Fix Status in linux package in Ubuntu: Incomplete Status in xserver-xorg-video-intel package in Ubuntu: Triaged Bug description: X locks up periodically for a 2 to ten seconds at a time and this crash log gets generated. It's significantly more than several times a day but not quite continuous. If you indeed have this bug, that should stop the lockups from happening. Irrespective, please file a new bug report so your hardware may be tracked. WORKAROUND: Edit your /etc/default/grub from: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.semaphores=0" run the following and reboot: sudo update-grub The side effects of this is rendering throughput is dropped by 10% with SNA, or as much as 3x with UXA. OpenGL performance is likely to be reduced by about 30%. More CPU time is spent waiting for the GPU with rc6 disabled, so increased power consumption.
