Comment 231 for bug 541511

Alban, there is warning of this bug in the release notes: http://www.ubuntu.com/getubuntu/releasenotes/1004#Intel%208xx%20X%20freezes/crashes

It's also a bug in the upstream code that every distro pulls from, so it's going to affect every linux distro in existence. You can't escape it by switching to another distro. But since it's so sensitive to timing, just about any change you make can affect whether the bug is frequent or rare.

But the bug still exists and your system could freeze at any moment, up until the final fix is released.
