Did you build with "-DDEBUG_ON_SERIAL_PORT=TRUE" to enable the debug
to go to the serial port?

Personally, I'd recommend *not* using DEBUG_ON_SERIAL_PORT, and
instead of looking at tty0, add this to the qemu command line:

-debugcon file:debug.log -global isa-debugcon.iobase=0x402

Then debug.log will contain the debug messages.

(BTW, thanks Laszlo for implementing this! :)

Yeah. This is more up to date than the Ubuntu wiki. It also has the
debugcon info...
