I wouldn't even have noticed, except I have ubuntu 10.04 installed twice. One auto-updated its kernel to 2.6.32-35 ages ago. But the other is still on 2.6.32-34, and doesn't seem to think it needs to update.

2.6.32-35 is there in the /boot directory. But it doesn't show up in the grub boot menu. I tried "update-grub", but that didn't seem to work. I also tried installing a couple of things, but that didn't work either.

Any ideas what's going on?
