dmesg

After 30 minutes or so my display goes black and I can see my desktop
environment (KDE) crashed in dmesg. See attached dmesg and Xorg.0.log. Please
ignore all the v4l related noise in the dmesg as it's from a custom compiled
kernel and not the stock Arch Linux kernel I'd normally use.

This has both happened with kernel 3.18 and 4.0-rc3. The severity increased on
the upgrade to xorg 1.17
