Is anyone else having this freeze/crash/kernel panic?

It's happening to me on SKL-X / FirePro W5000, as well as Haswell / R5 240, with the latter being to a much lower degree. It mostly only happens in GPU-heavy workloads e.g. iMovie, but on my SKL-X machine, it sometimes happens during normal usage too.

Both GPUs are getting acceleration and VDA Decoder is reported as "Supported" in HackinTool.
