With Nvidia GTX 650 Ti on Arch Linux using kernel 3.19.2 and xf86-video-nouveau
1.0.11-3 sometimes random hangs happen which locks up whole kernel. Screen
stays frozen and mouse cursor can be moved, but nothing else, even numlock
doesn't respond.

Any idea how to find cause? why it hangs...

I'm having the same issue here. Same card (GTX 650 Ti) on Arch, presently on
kernel version 4.0.5. The last journal entries after each freeze are
consistently:

kernel: nouveau E[   PFIFO][0000:01:00.0] write fault at 0x00002a0000 [PTE]
from GR/GPC0/PROP_0 on channel 0x007f96c000 [Xorg[383]]
kernel: nouveau E[   PFIFO][0000:01:00.0] PGR engine fault on channel 2,
recovering...

Except the channel number which is different every time.
Everything except the mouse cursor freezes, while sound also continues for a
few seconds before stopping. However, I can login from another machine via SSH
and restart SDDM just fine, although it takes about half a minute (from the
usual 2-3 seconds).
I'm using KDE and although it happens randomly, there seems to be a
correlation
with having Kaffeine playing TV in the background. No consistency, though.

Bug 90453 could be relevant, although the error messages are different.

Looking at the "fail set_domain" messages you're likely hitting
bug 92077. Take
a look at the patch/discussion in there please.
