Karmic Koala doesn't actually add the kernel to menu.lst
I had sever issues this morning after last night’s upgrade from Ubuntu Jaunty to Koala. Xorg was constantly at 98%, sound was broken, and the whole system was completely unresponsive.
Looking in /boot/grub/menu.lst I noticed the upgrade hadn’t actually added the new kernel at all. So I copied to config for the previous kernel and updated it to the new 2.6.31-14 kernel and on reboot we have sound and Xorg is now playing nicely at about 2% CPU. Panic over.
