I've upgraded from Freebsd2.0 to Freebsd 2.1R on a 486-66. 
I'm getting the above message on sio1 which has a USR courrier
attached via a 16550 serial port and pppd (pppd in the kernel).

Things seem to work well except i see this overflow message 
appearing daily. I wasn't getting this message when i ran 
v2.0 on a 486-50 but it had a different serial card in it.

the exact error message is:

/kernel: sio1: n(some number) interrupt-level buffer overflows (total 
some #).

I'm not certain whether i need to yank the serial card or work on the 
software or just ignore it. (maybe it is just someone flood pinging me).

thanks,

dave
