I'm using Ubuntu 6.10 and had the same sympthoms everyone else. I followed comment #23 but it was not sufficient. Swap worked fine but hibernate didn't. After re-iterating I added the entry on menu.lst (like comment #50 recommended):
resume=UUID=<uuid from partition> And now it works. -- After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature) https://launchpad.net/bugs/66637 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
