I can confirm this bug on upgrade to lucid from karmic.
rebooting with kernel 2.6.31 fixed the issue - although I had to edit /etc/default/grub and comment out the following 2 lines to be able to choose the kernel at boot:
#GRUB_HIDDEN_TIMEOUT=0 #GRUB_HIDDEN_TIMEOUT_QUIET=true
after editing /etc/default/grub, I had to run:
sudo update-grub
