It appears the problem is most likely this:

[ 989.990] (WW) modeset(0): flip queue failed: Device or resource busy
[ 989.990] (WW) modeset(0): Page flip failed: Device or resource busy
[ 989.990] (EE) modeset(0): present flip failed

[ 990.122] (WW) modeset(0): Page flip failed: Device or resource busy

[ 990.147] (WW) modeset(0): flip queue failed: Device or resource busy
[ 990.147] (WW) modeset(0): Page flip failed: Device or resource busy

where the Xorg 'modeset' driver is trying to talk to the kernel 'nouveau' driver.
