Subjecteepro100 driver (2.4 kernel) fails with S2080 Tomcat i815t motherboard.
I have a Tyan motherboard (S2080 Tomcat i815t) with 2 built-in NICs.

The manual claims this:

"One Intel 82559 LAN controller
One ICH2 LAN controller"

Seems that the eepro driver tries to bring up both of
them, and fails to read the eeprom on the second one it
scans. One visible result is that the MAC is all FF's.

I have two other EEPRO NICs in the system, and they seem to be
detected first.

The kernel is 2.4.10-pre11:
[root@lanf2 /root]# dmesg | more
Linux version 2.4.10-pre11 (root@lanf2) (gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-85)) #3 Tue Sep 18
10:07:01 MST 2001
The same problem is appearant with RH's 7.1 kernels (the upgrade 2.4.3* too).


Here is a pertinent part of the dmesg. eepro100-diag messages
follow below, along with an 'ifconfig -a'.

The kernel is 2.4.10-pre11:
