dmesg and crash dump

I was still experiencing a few system freezes with NVIDIA driver 349.12beta
(90% sure it was related with graphics) so I updated to 361.42. It seemed ok
but after a resume all the GTK-based graphics was trash (e.g. window
decorations and file dialogs are not painted at all). I had a look to dmesg and
I have again the

"GPU HANG: ecode 8:0:0xfffffffe, in Xorg [1284], reason: Ring hung, action:
reset"

It happens everytime after suspend and resume. It seems ok with a fresh boot.
Same problem with 364.15 beta.

Kernel was updated since the first submission:
