On older EEE pcs (Intel Atom graphics) current kernels fail with a BUG_ON
in i915_gem_object_create_stolen_for_preallocated.

Kernel 3.14 is reported to be working okay.

Here is an example trace, with 3.16.3:

Hardware from different reports:

D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller [8086:a011] (prog-if 00 [VGA
controller])

>From my uninformed quick look, the BUG_ON seems to be an assertion for memory
alignment. Any chance that this assertion does not hold on this hardware?

For further details, please see the full user reports at:

http://bugs.debian.org/764528
http://bugs.debian.org/771227
http://bugs.debian.org/768027
http://bugs.debian.org/763155

These may or may not be the exact same issue - some report that modeset
temporarily helped, some linked form posts say it's backlight issue; but above
BUG_ON can be found in at least two of the reports, and seems to persist in
early 3.17 versions.
