Hi guys,

I recently installed FreeBSD on a second partition of my hard drive. So far
everything works fine EXCEPT my mouse. I have a serial mouse, standard 
Microsoft or mouse system compatible. I am attempting to use it on mouse 
system setting. When I enter x-win everything seems fine until I use my 
mouse. I then receive the following messages printed to every xterm which is 
initially opened. The following messages occur only when the mouse is being
utilized. If the mouse is sitting still, I do not receive any messages.

NOV 21 20:31:48 myname /kernal: sio0: 253 more interrupt-level buffer overflows
(total 253)

NOV 21 20:31:48 myname /kernal: sio0: 253 more interrupt-level buffer overflows
(total 253)

NOV 21 20:31:48 myname /kernal: sio0: 5906 more interrupt-level buffer overflows
(total 6159)

NOV 21 20:31:48 myname /kernal: sio0: 5906 more interrupt-level buffer overflows
(total 6159)

NOV 21 20:31:48 myname /kernal: sio0: 230 more interrupt-level buffer overflows
(total 6389)

NOV 21 20:31:48 myname /kernal: sio0: 230 more interrupt-level buffer overflows
(total 6389)

and sometimes I receive the error
NOV 21 20:31:48 myname /kernal: sio0: 253 more tty-level buffer overflows
(total 253)

I am stumped as to the messages. Needless to say, my mouse does not work correctly.
Things can even get violent at times. No, the mouse did not work correctly during
the XF86Setup program. The mouse moves down ok, but when the mouse goes up it jumps
to the top of the screen. The three buttons all work correctly. Also, the rate of
movement is extremely fast.

My system contains a serial card. The original serial ports built into the baseboard
are not recognized by FreeBSD 2.2. I placed the card in and everything worked fine.
The serial ports are recognized. I have the standard sio configuration which is 
set by default.

I would appreciate anyone giving me some direction on this issue. Thanks in 
advance.

Regards,
	Wyatt
