I've always saw this bug after many suspend-resume cycles (interlaved with "real work"). Since testing one kernel in normal usage scenario would take many days I've tried to immitate "real work" by lots of memory intensive/fragmenting processes. Hovewer, this bug shows itself (sooner or later) in every kernel except 2.6.30 (or earlier).
