The messages I see on suspend to disk are like the ones described here <https://launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/78634>, where suspend works fine. So they may not be of interest.
I attached a kern.log.0 in case it's useful. ** Attachment added: "kern.log.0" http://librarian.launchpad.net/6469303/kern.log.0 -- Suspend broken on upgrade to Feisty 2/03 with Sony Vaio PCV-RX850 Desktop https://launchpad.net/bugs/83095 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
