It looks like this has been fixed in the latest -nightly, could you retest?

CC'ing Paulo for any clues regarding HSW.

Can you please retest? Also let's restrict this to the timestamp mismatch bug, please check that the failure matches in igt. I'll adjust the summary.
Also the bug that blocked bisecting (bug 79108) is fixed now in igt. So bisecting should be possible with latest igt but different kernels.
