console

Ubuntu 10.10 Server x64 installed as Virtual Box VM.

Fresh install plus postgresql and tomcat6 installed via aptitude. Rebooted the server and now when I run some command the console hangs. For instance, I run "sudo shutdown now" and then nothing happens but I am not returned to the prompt. I hit CTRL+C and nothing happens except ^C appears on the following line. I can type whatever and it will show up inline.

I switch to tty2 and try to login and I only get as far as [username][enter] and that console hangs.

One other thing - after "sudo reboot" the console appears to hang (just like above) when shutting down tomcat6.

Any idea what's going on or what I should check?

Thanks!
