Description of problem:
The RedHat startup-script says it initializes eth0 fine but this is NOT
true. The driver/module for the DEC 21040 / Tulip network adapter
is BROKEN on RedHat 7.1. The card looses the connection to the hub/switch
when it's initialized by the start-up script.
Steps to Reproduce:
1.Boot with the 21040 adapter in the machine
2.Do ifdown eth0 to down the network adapter
3.Do ifup eth0 and it fails to load the module.
Actual Results: Nothing - which is the problem ;) My network adapter
still doesn't work.
Expected Results: The module should have loaded and networking worked.
It's pretty bad that anaconda / the installer finds and configures the
network adapter at installation time, but the card doesn't work.
This is related to drivers, changing to kernel component.
This might also be a local configuration issue; check:
1) dmesg output when loading the driver
2) whether your switch is using autonegotiation (probably yes); if not, you need to tune /etc/modules.conf
3) 'lspci' output; which driver is used?
4) 'mii-tool -v'.
Also, does the de4x5 driver work instead of the tulip driver work ?
