Just to add my findings to this, the i915 fault also appears on a Ubuntu-Mate install but apparently recovers from it to log-in and run correctly.

Boots 3.16.0-6 amd64 fine, runs compiz 3D fine. Today's amd64 iso download, 20 August, boots to desktop & cursor. No unity. Did ubuntu-bug from command line on the booted iso, saved report.
