Comment(by andy):
What happens if we read the level of the EINT for PMU as GPIO input at the
end of suspend, and abort the suspend (ie, resume) if we see it is active?
What happens if we turn PMU interrupt to level instead of edge?
Previously it made trouble but that was before 2.6.24 and we never really
understood the mechanism anyway. Maybe just using level will clear this
issue (by forcing wake from EINT under these circumstances).
