dmesg-4.1.5

All is fine with version 4.0.5, upgrading to 4.1.5 gives reproducible gpu
crash. It crashes immediately as the driver is loaded. I'm attaching the full
dmesg output, the relevant part is at the end. I'll also attach
/sys/class/drm/card0/error. Here's lspci's output for the graphics in case it's
relevant:
