Subject: VGA resume & thaw (wake up from S3 & S4) broken - kernel exclusively

Actually I have nothing to show cause logs are all OK.
Haha, it seems to me that the bugs become intelligent.

Logs(dmesg) are literally identical.

3.15.10-201.fc20.x86_64 - nouveau(fb) resume & thaw PASSED, and that's all what works.
        Kernels >= 3.16 - nouveau(fb) resume & thaw BROKEN
            ALL Kernels - vesa(fb)    resume & thaw BROKEN.

Have a nice weekend folks.
