Hitting a key is what happened 2 seconds before this crash. Including the entire journal output. Two call traces are there, maybe the first one caused the instability leading to the first. I was able to login remotely with ssh; but the keyboard and mouse were unresponsive after this oops, I couldn't get to a VT. 4.8.17-200.fc24.x86_64 Parameters i915.enable_guc_loading=-1 i915.enable_guc_submission=-1 are used for this event.
