That link did not really work for me, but I think I found the right
place after a few clicks.

Just FYI, I proposed a discussion on the issues that create such a large
power gap between a CPUIdle-only system and a system with suspend (with
the assumption that the lowest C-state can be hit by both).

I don't really want to present a formal lecture on it, but it would be
nice to discuss with the group what can be done to shrink that gap a
little in kernel space (badly behaving timers in platform-independent
code) and in userspace (power-aware timers, coalescing timers, etc).

This is not intended to be another suspend-blocker discussion, but more
of a discussion on what it takes to get CPUIdle to be more effective.

Regards,
Mike
