The mission information is which CONFIG_* option changes the behaviour. (or maybe it's in the bugzilla, i just skimmed it very quickly) presumably it's either hibernation or memory hotadd that introduces the problem. My patch just allowed to have both together. Once it's determined which one it is one could do a second bisect with that option always on (and the other off)? Or maybe it's not a regression. -Andi
