Public bug reported: 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/grubx64.efi 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.
