We have a lab with different generation of Intel CPUs, starting at core2duo, first i-series to third generation i-series. We have the exact problem described here but only with the first generation i5-CPUs. Others work fine.
I have tested 4.4.0-36.55 (afaik proposed right now), the 4.4.9 mainline and the 4.5 mainline. I can confirm that the latter one fixes the problem. Is there any chance the patch will make it into 4.4.0 anytime soon?
