With i915.enable_rc6=0 the result is the same (with dmesg saying [drm] RC6 off).
FWIW, I get the same hang on my NUC6i7KYK with TF2 and Kerbal Space Program. With TF2 it happens reliably within ~10 seconds of entering the game. Sometimes it brings down the whole machine (unresponsive until reboot). I'm running Linux 4.7.0-994-generic from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/2016-07-05-yakkety/ I'd be happy to file a separate bug report if that would help someone troubleshoot this.
Same issue here. GPU hang while in CSGO_LINUX64. It do not happens always, so I can't provide steps to reproduce. Last time it happened, I was watching (in-game) a live from CSGO championship.

There may be a chance that this is a manifestation of https://bugs.freedesktop.org/show_bug.cgi?id=96175. Does upgrading your Mesa version do anything for you?
Upgrading to Mesa 12.0.1 (The 12.0.1-3 packages from Debian experimental) seems to have fixed the problem stated in my initial post at least, yes - Great! Will test some other programs and maybe newer kernel than 4.6-series again, will report back if I get it to crash with the same error as before. But if not, consider the issue resolved for me at least. Thank you very much.
Tested a few other heavy games, as well as running on Linux 4.7 again, all works great. I'm unsure about what Status you want, I'd call it RESOLVED and WORKSFORME, pardon me if that is incorrect.
