First-time installation, no legacy from prior versions. Hardware: Asus P4C800 Deluxe, latest BIOS 1021.005 08/04/2005 Easily reproducible. Immediately after installing Ubuntu Desktop, started getting freezes in the GUI. Usually happens within a minute or so of using the GUI after boot-up. The system is unusable this way. I am willing to make the machine available for remote or local (in silicon valley) debugging. ADDITIONAL INFORMATION: Anecdotally, I noticed that if upon boot-up, I first launch the command-line console (CTL-ALT-F1), log into the console, then switch back to the graphical console (CTL-ALT-F7), then I am able to use the GUI for a couple of hours through normal shutdown without kernel crash. I observed this all of the 3 or so times that I did CTL-ALT-F1 and CTL-ALT-F7.
