Minor clarification -- bug becomes difficult to reproduce _quickly_.

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).

Thanks.
