Bad flicker on skylake HQD due to code in the 4.7 merge window

2016-05-30 Thread James Bottomley
I've tested a pristine 4.6.0 system, so it's definitely something that went in during the merge window. The flicker isn't continuous, it's periodic, with an interval of something like 2-5 seconds. It looks like an old analogue TV going out of sync and then resyncing. I've attached the dmesg and
