I see:

eth0: DC21041 at 0x1080 (PCI bus 0, device 4), h/w address 00:80:c8:5a:f8:5b,
and requires IRQ29 (provided by PCI BIOS).
de4x5.c:V0.540 1998/7/5 davies@maniac.ultranet.com
eth1: region already allocated at 0x1080.
eth1: region already allocated at 0x1080.
eth2: region already allocated at 0x1080.
eth3: region already allocated at 0x1080.
eth4: region already allocated at 0x1080.
eth5: region already allocated at 0x1080.
eth6: region already allocated at 0x1080.
eth7: region already allocated at 0x1080.
Sending BOOTP requests....eth0: media is TP.
OK
IP-Config: Got BOOTP answer from 10.0.24.14, my address is 10.0.24.8

with only one 21041 board on PPC.

Caused by the `probe multiple times for multiple boards' changes.

On Zorro (e.g. Ariadne), the zorro_find() routine just skips boards that are
already configured. pci_find_*() doesn't.

Greetings,

Geert
