Comment 70 for bug 205990

I had this problem with an upgrade to Hardy Heron, but only with the latest kernel. Reverting kernel to the previous one worked fine.

The fix given at the top of this bug worked for me; the UUID for the swap file was correct in /etc/fstab but wrong in /etc/initramfs-tools/conf.d/resume. Editing this file to the right value and then updating initramfs has cured the problem.

I don't know how the UUIDs got out of step; the system was repartitioned using the gparted live CD immediately before the upgrade from 7.10 to 8.04, but the swap partition wasn't changed at that point; also, reverting to the previous kernel version worked fine (presumably the associated ramfs image still held a correct UUID?).

Thanks for the solution anyway. I have little doubt that resume will now work (should I ever choose to try it...)
