I have beeen looking:

====
sio%d: silo overflow.  Problem in the interrupt handler.  

sio%d: interrupt-level buffer overflow.  Problem in the bottom half of the
driver.  

sio%d: tty-level buffer overflow.  Problem in the application. Input has
arrived faster than the given module could process it and some has been
lost.  
====

Not sure about how to debug this, problem seems to be in the sio driver. It
could not be 100% compatible with serial in Xircom :\
