Comment 45 for bug 66637

To Scott: It happened to me just after the upgrade, and I do not remember having used manually mkswap before the breakage.
Nevertheless, I have to say that the upgrade failed midway for me, and I had to recover the system via a quite convoluted live-cd / manual mount / chroot and apt-get magic, so maybe in the meantime something strange happened. What I know is that I first noticed the problem due to inability to suspend-to-disk (aka hibernate).
