Hi,
I have a strange problem with 2.0.36/37 and the tulip-driver (the version
coming with the kernel as well as 0.90).
The hardware is a asus PB2-F (Celeron) with 5 d-link 530CT+. Four of them
are connected to BNC, the first one to a hub.
I assigned fixed IRQs to the pci-slots.
Now, when booting, only the first card (TP) is properly recognized by the
driver. For the other ones it reads 00:00:00:00:00:00 as MAC-address. It now
believes these 5 cards are a multiport card:
card 0: properly recogniced, correct MAC-address, correct IRQ
card 1: MAC-address read is 00:00:00:00:00:00, driver uses the
one of card 0 + 1, IRQ of card 1
card 2: as card 1, but card 0 + 2
....
Of course interface eth1 - eth4 now don't work very well (you need to send
packets to eth0 to get the other interfaces to receive).
(cat /proc/pci shows the correct IRQs of the cards).
The funny thing is: if you disconnect the BNC-segments, the driver can read
the MAC-address of the cards, so that all cards get recogniced correctly. Then
you can reconnect the segments.
This workaround is not really acceptable.
I did not observe this problem with any other of our routers, even an identical
pc (but 2 cards less) does not show this one.
Any idea?
Thanks,
Wolfgang Walter
