[realtek] unresolved symbol pci_drv_unregister

[Christian Bellmann]

Hi List,

after typing "modprobe eth1"

(in /etc/modules.conf is "alias eth1 rtl8139)

I get the errormessage:

.../rtl8139.o unresolved symbol pci_drv_unregister
.../rtl8139.o unresolved symbol pci_drv_register

 ..... failed

what have i made wrong??
I try to use this realtek card as my second network card 

Thanx

Chris
