You'll probably find that fish is running, and waiting for input on the serial port. If you want it to come out on the console, there are a series of hacks of dubious quality that enable this: You need to comment out the serial module, run the lpc_kbd driver instead, and pass "keyboard" as an explicit command-line argument to fish. Even then, you'll find that the cursor doesn't move (because we don't bother to update it) and that the keymap/console handling is laughably incomplete. Basically, it's just barely enough for a demo where I once started the slideshow program from the console... feel free to improve it if you like, but what we really need is a form of console/tty abstraction layer.

Blame ACPI complexity for this one... it last worked for me on an X301, but obviously hasn't been tested in a long time. Again, not high on the list of priorities :)
