Very good point. As far as I can tell, laptop-mode doesn't do anything
in particular at all when the computer is suspending. If there's an
explicit sync I think it should do the syncing, otherwise I think your
scenario is quite possible. (Not one I thought much about, to be honest,
since my notebook stubbornly refuses to wake up from suspend so I have
given up on it for now, although I retest it with new kernel versions.)
Perhaps it would actually be possible to sync just before actually
suspending in the suspend script?

I'll check if the upstream maintainer of the laptop-mode tools has any
input on this.
