Public bug reported:
My Lenovo 3000 N200 laptop, running Karmic Beta has taken to
unpredictable behaviour with regard to suspend.
This bug report appears to have been triggered by the laptop going into
suspend mode for no apparent reason. It did wake up normally on use of
the power switch.
Other unstable behaviour recently has included waking from suspend on
opening the lid, but then promptly going back into suspend. Again,
using the power switch recovers the system ok.
ProblemType: KernelOops
Annotation: Your system might become unstable now and might need to be
restarted.
