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:

Linux 4.0.0-040000rc6-generic #201503291935 SMP Sun Mar 29 23:36:50 UTC 2015
x86_64 x86_64 x86_64 GNU/Linux
Ubuntu 14.04.4 LTS
