conflicting network-cards?

[Joerg Huber <huberjoerg@web.de>]

Hi,

After the configuration of a second ethernet network card
I got the following error messages in /var/log/messages: 

> eth0: unexpected TX-done interrupt, lasttx=20
> eth0: mismatched read page pointers 4c vs 51

But eth0, the first network card, seems to work properly. 
These messages are written repeatedly after eth1 is configured with 

> ifconfig eth1 0.0.0.0 up

I would like to use the second NIC to connect to an ADSL-Modem, but when I
start pppoe for testing the ADSL-connection with 

> pppoe -I eth1 -A

i get the error message 

> pppoe: Timeout waiting for the PADO packets

But I know that the ADSL-Connection is physically working.

The NICs are both of the same type (NE-2000 compatible). 
eth0 is on IRQ 5, eth1 is on IRQ6, the machine is a 486 and I would really
appreciate every hint on whats going on here.

Bye,
