Description of problem:

When system is suspended/asleep, resume occurs as expected when opening lid.  However, the desktop flashes briefly and then system suspend initiates immediately and cannot be avoided.  Closing lid and reopening has no effect; the power button must be pushed, which occasionally results in unintended power off.

Version-Release number of selected component (if applicable):
Unsure which component is responsible.

How reproducible:
Has occurred every time since upgrade to F18


Steps to Reproduce:
1. Suspend system
2. Try to resume
3.
  
Actual results:
System must be manually resumed a second time.

Expected results:
System should resume and allow login to existing desktop session.

Additional info:
I see quite a few reports of this against F17, but I never experienced this behavior with F17.
