Subject: sio overflow problems with adding a fourth port.
Sender: questions-owner@freebsd.org
Precedence: bulk


I currently have a card with 3 serial ports on it. I am trying to 
add sio3 on another serial card.  All other ports on the second card are
disabled and no device is hooked up to sio3 yet.

With this setup, I get lots of sio overflows on sio2 (a US Robotics 28.8
modem).   The only time this didn't happen was when I dialed out without
bothering to startup X.  Am I doing something totally stupid.  Any
ideas?  This is with FreeBSD 2.0

Thanks
Mark
