It is running SMP on a SMP machine, which is all SCSI machine connected
to BusLogic 958. It has a Tulip network card. It doesn't run X. One
thing I didn't mention. I am not sure if it is related. Since I
upgraded to 2.1, I need several tries to setup my CSLIP link. Sometimes,
the link will die immediately when the connection is made. Sometimes,
the line is connected, but ping doesn't respond. I have to bring the
link down and try again.

BTW, 2.0 seems ok on the same machine.
