The radeon drm driver with kernel mode-switching in the new 2.6.34 kernel does not release the AGP bridge when suspending a laptop. The result is that a system running X cannot resume properly. Only a reboot restores normal operation. Reproducible: Always Steps to Reproduce: 1. Start X (in my case, I use KDE.) 2. Close the lid on the laptop and wait for the system to finish suspending. 3. Open the laptop to resume. Observe that you cannot resume your X session.

Apparently 2.6.33 also exhibits this behaviour. Pass the radeon.agpmode=-1 parameter to the kernel at boot time to work around this problem.
