It didn't hang.  It switched to the serial console.  Just like it said.
That's why Ross added the warning in the code :-)

NetBSD doesn't yet have a fully-integrated display console driver for
that platform, tho an experimental one can be used with the TCWSCONS
kernel.  Unfortunately, with that kernel, the serial ports can't be
used for anything else (that's why it's still "experimental" :-)
