To resume from a hibernated image, the "/etc/initramfs- tools/conf.d/resume" file has to be filled with the information of the swap device also (which is a separate problem on a dapper->edgy upgrade) as mentioned in 66637. Please try it also and let us know whether it works.
There is also "resume" kernel boot flag which you can try -- Cannot hibernate after Dapper -> Edgy upgrade https://launchpad.net/bugs/70903 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
