I'd like to post an update to this bug report. For about two weeks now I've been running kernel 4.0.0-997-generic #201503310205 SMP Tue Mar 31 02:07:04 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux which I got here http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/ I've also installed xf86-video-intel driver version 2.99.917. All of this was from the assistance of the Intel-Gfx mailing list. Other than having to reboot last week when a new standard Ubuntu kernel came down which was after 6 days of no lockups the system has been stable. Currently I'm again at 6 days, 5hrs with no lockups.
