[Apple Computer, Inc. Macmini1,1] hibernate/resume failure

[Peter T Hayward]

Binary package hint: uswsusp

Hardware: Mac Mini Core Solo 2GB RAM
Software: Kubuntu 9.04 up-to-date
First test of Suspend-to-RAM-Resume worked OK, then Hibernate-resume, which failed.
Clicked to Hibernate and the front panel LED went out, but the disk continued to run and the screen showed the desktop. No mouse pointer and no life from windows or clock.
I powered down and restarted, apparently normal then the bug report prompt appeared.

ProblemType: KernelOops
Annotation: This occured during a previous hibernate and prevented it from resuming properly.

Exactly the same behaviour again after 500M recent updates, inc kernel 2.6.28-11-generic and kde 4.2.2.
