dmesg from crashing kernel

Hello, I have been experiencing crashes when using nouveau and compton, using
i3-gaps as a tiling WM.

Machine responds to SSH, but the X desktop freezes and e.g. numlock does not
respond anymore.

I can't manage to reproduce the issue when compton is not started. I have found
a relatively reliable way to reproduce it:
1. Start firefox, xterm
2. Mod-shift-Q to close xterm
3. (optional?) Mess around firefox, create and remove tabs etc
4. Start xterm, start over from 2
Eventually, the desktop will hang on step 2 and switching to a TTY becomes
impossible. Machine still responds to SSH.

I am running Arch Linux with:
linux-ck 4.14.12-3 (from AUR, compiled today)
mesa 17.3.1-2
xorg-server 1.19.6-2
xf86-video-nouveau 1.0.15-2
libdrm 2.4.89-1

$ uname -a
Linux sdelang-arch 4.14.12-3-ck #1 SMP PREEMPT Sun Jan 7 16:31:01 CET 2018
x86_64 GNU/Linux

Thanks!
