error state with nightly

Running TUtM webgl demo on chromium results in system death, but i915.reset=0 lets me get the error state from it. This using nightly from yesterday:

http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/2015-08-13-unstable/

distro is Ubuntu 15.04 updated to current, but chromium downgraded to 41.x so that webgl works, maybe some config option needs to be turned on too..

Reproduce steps:
- open chromium
- go to
https://www.chromeexperiments.com/experiment/a-trip-under-the-moonlight
- open the demo
- after grabbing the ship with left mouse button, move it around rapidly for a few seconds

oh, first you need to install chromium:

apt install chromium-browser=41.0.2272.76-0ubuntu1.1134

looks like this version has webgl enabled by default, the newer version has it permanently disabled AIUI


My SKL-H is MBSH1SEVA SDP, gpu rev04.

More tips to reproduce: Zoom close in to the center mast of the ship so that the center sail is about 50% visible. Spin it around rapidly with left mouse button. Hangs in few seconds.
