[Beignet] Unit test fail (and regression?) on i7-4702HQ

[Zhigang Gong]

It's weird that only that case failed. Did you check whether a GPU
hang occurred?
And did you try to reboot your system to run the unit tests again?
Sometimes, if the GPU hang once, it may not be able to fully recover to normal
state without a reboot. Just in case.
