pm-utils hibernation code does not differ much between f7 and f8.

My analysis is pure speculation based on my understanding of how you can
tune that behaviour with suspend2(tux-on-ice).  But it is very noticable
and very annoying and very clearly a f7->f8 change.

I guess it is then a change in the kernel, but afaik the f7 and f8 kernel are very similiar, too.

Just for the benefit of future web searchers with the same question, here is an interesting thread covering the specific issue. My real curiosity is still why the performance I see regressed so badly when I upgraded to F8. The thread leads me to believe that the the F7 swsusp1 did not save caches. Hmm... I have been enjoying the convenience of fedora's suspend-works-out-of-the-box for awhile now, but I think it might be time for me to go back to tux-on-ice. I truly am disgusted by having to suffer through 5-15 seconds of thrashing while changing desktops after resume. I would much rather the resume take 20 seconds longer, and present me with a good user experience. (yes, I am one of those people that thinks that offering early login while the system finishes booting is a really stupid thing).
