I’m running a Kubuntu 15.10 installation and trying to use nvidia driver with my GTX970.
So after booting the system after some random time(usually just a few minutes), graphical system completely crashes, I’m not even able to switch to a console, afterwards.
Kernel is still alive though, as I can reboot the machine through SysRQ-Keys.
This is the error i could pull from dmesg.

Sometimes it happens without the bit error too.

Usually I would suspect any hardware/power supply issue, but some recent games on the same machine when using a windows 10 installation work just fine, so I’m suspecting it must have something to do with the nvidia-driver on linux? Nouveau driver doesn’t crash either. But that one is not using any hardware acceleration right?
Any help or hints highly appreciated.
