Check for cron or another app using 100% cpu - I had this awhile back
and it "seemed" to affect suspend time, but I think that was because it
chewed up so much battery that battery life overall seemed short.

I am using shr-t and it seems battery life is better if anything on both
the current (no debug/preempt kernel) and a modified version with even
more drastic mods (-O2 instead of -Os)

Which brings up - how can a user benchmark a kernel in a way thats
relevant for user tasks?
