If you're not using the eepro100 driver, then an insmod of the
netconsole driver will fail:

+       if (!ndev->poll_controller) {
+               printk(KERN_ERR "netconsole: %s's network driver does not implement netlogging yet, aborting.\n", dev);
+               return -1;
+       }

Maybe that message is in your logs somewhere?

Take a look at the poll_controller() implementation in the eepro100
part of Ingo's patch - it's dead simple.

What we need is for a bunch of people to implement poll_controller()
for *their* ethernet driver and contribute the tested diffs
back to Ingo.
