I am trying to have a 3c900 Combo work with my stock 2.0.28 kernel. I
replaced the original 3c59x.c with the which recognizes my 3c900. See file
header below:
------------start of file header-----------------------------------

A first problem I had was that the card/kernel did not autosense the use
of the 10base2 port. A quick hack was to hard code the fat that I want to
use that port by setting:
} else {
/* Aaaargh! Horrible Hack!... */
vp->media_override = 3;
/* vp->media_override = 7; */
vp->full_duplex = 0;
vp->bus_master = 0;
}
but then the card was working on 10base2 at system boot:

latency timer (CFLT) setting of 80, new value is 255.

*** NOW THE PROBLEM ***
All work fine for about 2/3 days. The net is heavily loaded as the
machine is running under shared /usr. Suddenly the machine will start to
output this message:
kernel: eth0: Transmitter access conflict.
And the machine is practically blocked (due to the shared /usr). Upon
reboot and inspection of /var/log/messages, the critical section lists:
----------exc. from /var/log/messages-----------------------

Please, help me shed light on this problem!
Thanks in advance,
