Public bug reported: updated to 12.10, tried hibernate again. I had not worked before, so not surprised it still does not.
Somewhere in upgrade dialogs I was nagged that resume=/dev/sda2 was not as safe as UUID, so I modified /etc/default/grub to use UUID. This seems to be passed correctly: $ cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-3.5.0-15-generic root=UUID=fe0028ac-92b7-4340-b092-114dfc31cb56 ro resume=UUID=d707be1e-544c-4221-83c5-f03140c655a5 ProblemType: KernelOops DistroRelease: Ubuntu 12.10 Package: linux-image-3.5.0-15-generic 3.5.0-15.22 ProcVersionSignature: Ubuntu 3.5.0-15.22-generic 3.5.4 Uname: Linux 3.5.0-15-generic i686 Annotation: This occured during a previous suspend and prevented it from resuming properly.
