I did more testing on my box. With the box in an idle state (~0% CPU load), I used a hitch-detection script (it prints a hitch error to stdout every time the system goes more than two seconds without scheduling the script) to try the following: After sudo /etc/init.d/gdm stop, and logging in at

Resetting the BIOS/CMOS (by selecting Load Optimized Defaults) appears to have fixed this issue. 5 hours so far with no hitches (freezes). I can't imagine why any BIOS setting would cause this issue with Ubuntu but I'm optimistic about the problem being fixed. IIRC this box is 16 months old. The
