Known issue, there is a potential fix http://marc.info/?l=linux-kernel&m=144753854913605 . Since this is just a warning and not a functional issue, I'm going to wait until it gets pulled into Linus' tree.
Description of problem: I switched to another TTY in order to install some packages. Then, I tried to go back to the original one but everything was stuck and I had to issue a forced shutdown.
