Bug description:
  Upon resuming from suspend-to-RAM, the system will start to wake, and
  will immediately go back to sleep.  If I cycle it one or two times
  more, it will stay awake.  I have reproduced this exact behavior with
  Jaunty on the new kernel as well as on Fedora 10
  (https://bugzilla.redhat.com/show_bug.cgi?id=475585), so it is not
  specific to Ubuntu.

  It has been observed that this happens when suspending via hotkey but
  not when suspending command (details in comments, below).

  As a conjecture, it is behaving as if due to some race condition it
  has not yet cleared  that it has a suspend event, so it immediately
  re-processes the suspend upon waking.
