Hmm, have you ever tried it when the console is a keyboard? Also the electrical glitch of unplugging a serial console can do this and as Perderabo already mentioned it was patched so the key sequence could be a little more complex resloving many of these issues. I have personally seen this happen in the past 12 months with the standard break enabled.

BUGS
The network synchronization between client and server instances is weak, and does not prevent incompatible options from being used on the
two instances. The method used for retrieving work completions is not strictly correct, and race conditions may cause failures on some
systems.
