Comment 39 for bug 1413440

Hmm, that's outright annoying. Do you resume from hibernate or from suspend?

I can only think of 2 other options to try:
- upgrade to a newer kernel (or even try downgrading - see what that does):
http://kernel.ubuntu.com/~kernel-ppa/mainline/

- use software suspend (uswsusp package). Configuring can be a bit tricky though, as the system suspend/hibernate commands are not automatically adjusted, so invoke hibernate manually by s2disk .
