The problem resides that the sio driver expect to see a real 16550 or 8250 chip, during the startup test, in the attach routine, and one of the tests fail. Solution: Modify the attach routine in sio.c (/usr/src/sys/i386/isa) there is a piece of code that makes 4 tests, recompile the code by doing a "printf" of the counter, and see where it stops, and ignore the situation.
