fstab entry:
UUID=b38faaf6-74a1-428d-a199-91ecbbd4c1a5 none swap sw 0 0

Have the exact same problem. Its not a fstab/uuid issue. What I've noticed is that when it fails and I do a sudo vol_id /dev/sda5. the output has "ID_FS_TYPE=suspend" instead of "ID_FS_TYPE=swap".

Once I do a mkswap and then add the new uuid to the fstab file, it starts to work on reboot until for some reason the ID_FS_TYPE get set to suspend again. Any chance this is related to hibernate ?

I had the problem where swap wasn't getting activated on boot, but my issue was that the UUID in /etc/fstab didn't match the vol_id on the swap partition.

How that happened I don't have any idea, but setting /etc/fstab to match the vol_id fixed it.

I had the very same issue as kenw: "the UUID in /etc/fstab didn't match the vol_id on the swap partition"

It is just after an upgrade from Xubuntu 7.04 to Xubuntu 7.10.

Swap partition failed to mount on resuming from hibernate with gutsy.
bala@bala-kubuntu:~$ sudo vol_id /dev/sda12

ID_FS_LABEL=
ID_FS_LABEL_ENC=
ID_FS_LABEL_SAFE=

I tried rebooting, on start up still got "Activate swap [FAIL]"

swapon didn't work either
had to format the swap partition and then swapon, whereupon it was back to normal

(I'm a newbie at Linux, and this is my first bug comment at Launchpad, so please excuse my ignorance if I haven't provided enough details.)

I've got the same problem after I used gpart to adjust my space. I might have changed the size of the swap partition after the operation. The swap partition failed to mount after the machine resume from sleep. Machine automatically restart with "activating swap fail" error... The problem loops every time I try to sleep my laptop.
