Dapper complete system freeze---could be 'ati' driver or epiphanybrowser

[Wenzhuo Zhang]

The symptoms on my ThinkPad X32 is exactly the same as yours. I filed
a bug report <https://launchpad.net/distros/ubuntu/+source/xserver-xorg-video-ati/+bug/55570>
earlier this month. I guess it's a duplicate of <https://launchpad.net/distros/ubuntu/+bug/50687>.

My laptop doesn't lock up anymore after switching to the vesa driver.
