Ditto. Got this now also on BDW GT2 with latest gfx stack / Iris.

I'm still able to reproduce the system hang on SKL GT2 (i5-6600K), just by
rebooting with latest git versions of gfx stack, and running the hanging test
few times:
bin/testfw_app --gfx glfw --gl_api desktop_core --width 1920 --height 1080
--fullscreen 1 --test_id gl_4
