serial troubles

[Matthew Dillon]

:	DF always sends messages like following, when I have an internet connection via my external modem connected to COM1..
:sio0: 1 more silo overflow (total 1)
:sio0: 1 more silo overflow (total 2)
:sio0: 1 more silo overflow (total 3)
:sio0: 1 more silo overflow (total 4)
:sio0: 1 more silo overflow (total 5)
:	I mean, it does not reflect on connection, but it is annoying...

    Yah, those are going to be around for a while.  There is a latency 
    issue in the interrupt subsystem somewhere... it isn't the scheduler,
    but more probably an spl or critical section being held too long
    or something like that.   I have to track it down but it is low priority
    at the moment.
