sio0 : silo overflow

[caleb]

Hi,
    I am having some problems with the serial port (si0) connected to my 
modem. Everytime I try to download a file I get the following output on 
my console;

kernel sio0: 1 more silo overflow

I thought it might be the baud rate but stty displays the following 
information;

speed 115200 baud
lflags: echoe echoke echoctl pendin
oflags: -oxtabs
cflags: cs8 -parenb
erase

I checked the config file for the 5.4 stable kernel I am using and the 
serial driver is enabled;

# Serial (COM) ports
device          sio             # 8250, 16[45]50 based serial ports

Is there another serial port driver that I could add to the kernel? Is 
the serial port the problem or is it my 56K dialup modem? The serial 
port is a 16550A based port.

compucomp# dmesg | grep sio0
sio0: <165550A-compatible COM port> port 0x2f8-0x2ff irq 3 flags 0x10 on 
acpi0
sio0: type 16550A

If you reply could you please cc me as I am not subscribed to the list.

Thanks,

caleb.
