** Description changed: Freshly installed 14.04.1-Ubuntu Desktop. 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), 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. + Anecdotally, I noticed that if upon boot-up, I first launch the command-line console (CTL-ALT-F1), 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. This make it seem like some sort of a reference-counting bug: if I run CTL-ALT-F1 at least once, then the problem doesn't happen.
