Hi all

perhaps this is not kernel related but since the message comes
from the kernel I mention it here:

while using slip over a dialup line i keep getting this:

May 29 03:51:17 tron kernel: TCPv4 bad checksum from 08119582:0014 to 0f02000a:102f, len=263/263/283

it seems that every activity like disk access causes a data overrun.
this sounds like a handshake error but (as I think) hardware handshake
is configured correctly.

thanks for help
