Well this just happened again to me with same PFIFO_CACHE_ERROR nouveau errors in dmesg. Although this time it happened on gnome-shell, which is my normal desktop where I have never seen this before. I have only had this happen on those rare times I try Unity. I had updated earlier today and noticed my kernel went from linux-image-generic-pae = 3.5.0.2.2 -> 3.5.0.3.3 and xserver-xorg-video-nouveau = 1.0.1+git20120628.0d2b414a-0ubuntu0sarvatt~precise -> 1.0.1+git20120702 .0d2b414a-0ubuntu0sarvatt~precise. At least we now know it is not specific to Compiz/Unity. Looks like a kernel and/or nouveau issue. Skype was running and I had music playing (via guayadeque) which I think has been true every other time this has happened.
