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
