Bug Description
Binary package hint: xserver-
When I attempt to suspend my laptop, it appears to suspend fine. However, attempting to resume results in a total lockup. The power light turns steady (as opposed to blinking in standby), the disk light blinks once, and the fans spin up, but nothing happens at all after that. I have to resort to a hard reset to "revive" the machine. After bouncing around various fourm postings, the culprit appears to be the ati (the open-source one) driver. My graphics card is a R200 based Mobility Radeon 9100, but i've heard of the issue with R300 series chips as well

I can verify this behavior on a 15" Apple G4 Powerbook (Radeon 9600 / r350) running Gutsy. Sleep *does* work as expected if X is not running.
