That's odd, your dmesg doesn't show any attempt to resume. Mine looks like this:
[ 3.002362] PM: Starting manual resume from disk [ 3.002365] PM: Resume from partition 8:5 [ 3.002367] PM: Checking hibernation image. [ 3.002560] PM: Resume from disk failed.
(that's normal when the system wasn't hibernated)
Are you using any kind of custom kernel or initramfs on this system?
