Hi Simon,

We went on to continue to debug using more debugging in userspace via MSDK.
This resulted in no further results, unfortunately.

During contact with manufacturer, we also found out that this motherboard,
X11SAT-F, has built in firmware which is apparently some kind of a PCIe
multiplexer, able do more PCIe lanes than the CPU is actually supposed to be
able to.
However, this is most likely now the cause of all kinds of instabilities and
issues with the onboard graphics card.

Therefore, we have sent back mobo to factory for them to have another look at
it.
I don't think this is an i915 / drm issue and will thus close the bug.
