Over the last three months this issue has occurred 3 times, with an approximate frequency on once every month. The error logged is from the Intel Management Engine driver (mei_me) right after resuming from sleep - could indicate some error with resuming from sleep state for the Management Engine.

Given that this error is potentially pointing to a device other than graphics and has very low occurance, I'm marking this as low priority. Also, the test during which this error is reproduced is also passing.
