Multiple kld loads?

[Jim Flowers]

With FreeBSD 4.8-20030731-STABLE #0, dmesg messages indicate:

module_register: module miibus/ukphy already exists!
linker_file_sysinit "miibus.ko" failed to register! 17
module_register: module pccard/ed already exists!
linker_file_sysinit "if_ed.ko" failed to register! 17

This doesn't look dangerous but the rl0 ethernet card just stopped recieving 
packets suddenly and I'm trying to track down why.  Can anyone tell me why 
this is happening and should I do anything about it?  I have installed 100s 
of versions of fbsd since 2.2 on this same hardware and this has never 
happened before.

I see this was reported on 7/25/03 but, no follow-up:

Thanks.
