Interesting... Yesterday I turned off my PE with no problems. Today, when I turn it on, it goes all the way to the 4 dots and then it stays there, flashing from time to time. It seems the boot up got stuck somewhere, but unfortunately I have no way of knowing where (I don't have the serial port open yet). It might be random, it might be a problem with the filesystem change, who knows...
I wonder if anybody has any idea on how to get a console with the boot messages. That might require a bit of "kernel magic"...
