No, it doesn't.  There is a patch that fixes it for a certain class of hardware that is Broadwell based.  Your machine is not Broadwell based, it is Haswell.

I'll try and come up with a kernel for you to test later today.
Comment 3 Josh Boyer 2016-01-22 13:23:05 UTC 
Please test this kernel when it completes:
