[Dell Inc. Studio 1737] late resume failure [non-free: fglrx]

It happened after a manual suspend. When resuming, I had access to keyboard (num lock could be activated/deactivated) and I had to CTRL + DEL twice to reboot and gain access to the display).

ProblemType: KernelOops
Annotation: This occured during a previous suspend and prevented it from resuming properly. The resume processing hung very near the end and will have appeared to have completed normally.
