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.
