Attached is more debug information after a freeze today. Earlier in the day, Ubuntu released updates which included some modified X packages. This freeze happened after those new packages were already installed and the machine had been rebooted. After the freeze I modified my xorg.conf to disable MTRR with "Option NoMTRR"
