Bug Description
plars discovered that after doing do-release-upgrade -d from a precise server image can result in what appears to be a frozen system. Input to the console works fine (you can log in and do things, and you can also ssh in if ssh-server was installed) but you see no output. jibel discovered that -vga std does not have this bug.
This could be a bug in the cirrus driver in quantal, or a bug in the vnc output in qemu-kvm, so I'm marking it against both.
