For starters, the reported errors from the dmesg require fixes from a much more recent kernel than v4.4. That will also include a number of require hw programming fixes for Skylake.

I was just doing what the error told me to in order to help. If you need any more info, I can provide it, if not you can close this issue. I'll upgrade when I can.

Hi Burak, your help is needed. Please update your kernel to the latest and let us know if the issue reoccurs. If it does make sure you update the logs.

then once providing logs change the status of the bug to reopen.

Timeout - assuming to be fixed. If problem still persist on the latest kernels (preferable with drm-tip from git://anongit.freedesktop.org/git/drm-tip). Please include also full dmesg from the boot (see https://01.org/linuxgraphics/documentation/how-report-bugs) , and the information about the use case you exercised during the failure. These thing will help us maybe reproduce the fault and then fix it.
