AMD Radeon hangs during hibernation - regression.

I'am using Arch Linux.
After upgrade the kernel from 4.6 to 4.7 I cannot hibernate my Lenovo g50-45
netbook - AMD a6 6310 with radeon r4 Beema.
When system is triggered for hibernation screem gets dimmed and netbook hangs.
I have to power it off by pressing for longer period of time the power button.
Fans are getting on full rpms and machine is getting hot.

Bisected changes and the first bad commit is - drm/radeon: hard reset r600 and
newer GPU when hibernating. (commit 274ad65c9d02bdcbee9bae045517864c3521d530)

Bios - file attached.
CPU info - file attached.
Log from boot/hibernate - file attached.
Bisecting log - file attached.
