Someone reported GPU hang with high media workload on BSW and provided a workaround in the gfx mailing list. Could you give a try? https://lists.freedesktop.org/archives/intel-gfx/2016-September/105710.html (In reply to haihao from comment #1) > Someone reported GPU hang with high media workload on BSW and provided a > workaround in the gfx mailing list.

(In reply to haihao from comment #3) > Does the fix in kernel work for you ? No, We have tried but have no effect.Is there any tools to debug this type(GPU hang) of issue? Normally it is hard to identify the root cause for GPU hang issue without any details. You are using Kernel 4.2.0, could you try the latest rc kernel? If you can produce this issue with the latest rc kernel, please provide the steps to reproduce this issue and /sys/kernel/debug/dri/0/i915_error_state. |
