Comment 8 for bug 359245

I believe this is the same issue I ran into with 9.04 after attempting to upgrade from 8.10. I would experience lockups where the screen was frozen and nothing moved but the mouse, or sometimes the mouse would stick too. There was no way out of these other than a hard reset.

Back to running 8.10 now and it is stable - no freezes.

If my issue is the same, it cannot be the intel problem as I am not running any intel hardware. My machine has an AMD64 chip, and nvidia video. The freezes happened with both i386 and amd64 versions of ubuntu 9.04.

Could be the same as this "strace" bug: #364524
