threex: takes 15s to start if power cycled quickly

[sshane]

discovered on my desk, not sure if this is intended or not. if you unplug the device, then quickly plug it back in within a second or two, the display remains blank + no serial output for 15s, then I see:

tici login: panda disconnected!
no pandas found
no pandas found

...

The first thing you see on a normal boot is:

is it hitting a different code path when I do this?

It’s just shutting down first.
