Flushing all pending writes/journal entries is a good idea but I don't think it will solve the problem. The suspended kernel may also have clean disk blocks cached in memory when you suspend.
You may boot another kernel and change a file, which resides on one of these blocks the suspended kernel has cached.
Well, my idea was that if I once used a different kernel the swap space would be used by this kernel and thus there is nothing to resume from. Perhaps this was naive (as I wrote in the FAQ which I was pointed to the swap space was marked invalid).
I don't know that any of this actually happens -- I'm just guessing. Maybe SwSusp2 flushes all block caches (not just pending writes, but cleans out caches completely). Somebody please correct me if I'm wrong.
IMHO this would be reasonable - at least an option for those paranoid people like me would be fine.
Kind regards
Andreas.
