I'm suspecting that this is because of all the missing PM errata we don't have in the mainline kernel :( I think we're missing at least the following based on a quick grep of the Nokia patched PM code: - 3430 (and 3630?) hs omap cs1 off-idle bug where save/restore needs to be in lowmem - 3630 retention idle is missing errata handling for 1.85/i581 - 3630 off idle is missing 1.87 handling - smartreflex missing twl4030 errata? - Nokia patched PM code mentions also quite a few other missing errata such as 1.88, 1.142, i582, i467, i468, 1.164 This may be a bit out of date as it's based on some notes I made few months ago after I started noticing flakeyness on my 3630 zoom3 board.
