I am wondering if the stock examples are saused by something different, specifically the nook thinking its still charging when not connected. I just found it this morning in that state again (at least the second time I know of) and since it doesn't sleep on charger, obviously no deep sleep. (And before some idiot starts bashing me, no it was NOT on the charger, just acting as if it was: in battery use and in spare parts.I do not believe that the CPU scheduler is causing the lack of deep sleep. I've had reports of this from both the stock and the overclock kernel(stock uses CFS).
BFS got a bad wrap in the Android world early on because BFS was still very new at the time. It has matured greatly since then.
It also still seems strange that on vanilla nightlies, deep sleep works immediately and flawlessly for me, but I lose it without fail every time I put the oc kernel on.
Still awaiting suggestions from anyone on what to try capturing in my oc vs non-oc states here...
