My gut feeling is something in core 15 needs review?
FahCore_11 works on G80/Tesla GPUs (and used to work on early ATI GPUs before they were deprecated.) FahCore_15 works on Fermi and Kepler GPUs.
If you read all the discussions from Saturday, the Assignment Server was messing up and it assigned WUs for Fermi/Kepler when it should have been assigning WUs for G80/Tesla. It's not FahCore_15 that's the problem, it's a WU that was improperly assigned that doesn't work on your hardware.
