Bug Description
Upgraded to 12.04 beta 2 64-bit, but the keyboard and mouse (both USB) don't work. Unplugging the mouse and keyboard didn't work.
I have tried booting from an external 12.04 USB flash installation disk to try to mount the partition and continue the upgrade but the mounted partition contains only the following file:
EFI/ubuntu/
The output of "sudo fdisk -l" follows:
WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

I mounted the wrong partition, my bad. Using GParted Partition Editor I was able to see that the actual partition was sda2, not sda1. Weirdly enough though, fdisk showed only sda1 partition.
I was able to continue the upgrade, and fix the keyboard and mouse problem, by running the following commands:
sudo mount /dev/sda2 /mnt/linux
sudo chroot /mnt/linux su
mount /dev
mount /proc
mount /sys
apt-get update
apt-get -f upgrade
