It seems, that the same, or very similar bug is reported and investigated at:
1. https://bugzilla.kernel.org/show_bug.cgi?id=42844
2. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=644174

However both above reports suggested, that problem is limited to Dell Vostro 3750, and probably related to erroneous BIOS.
If this is a problem affecting broader class of machines, maybe the chances that it will be solved are better.

Is the problem you experience associated with i915 compatible GPU in your laptop?
Is the problem worked around if you boot your machine with i915.modeset=0 kernel parameter?
