It's a GPU hang. Please attach /sys/kernel/debug/dri/0/i915_error_state. Created attachment 78188 [details]
hung i915 error state
Sorry; should have said that this was also in one of those links.
Note that the GPU only hangs about half the time; the other half the time the error state is "no error state collected".

Xorg.0.log that accompanies i915_error_state
The backtrace from Xorg.0.log entered previously occurs when there is no i915_error_state; in the case that there is a i915_error_state, Xorg.0.log looks like this.
Upstream stable reverted the chicken bit removal rather than backport the correct driver code. |
