weird problem with 9.0 Release and ed0

The problem need not to be confined to 9.0. It stated to develop under 
5.1 already.

I'm running a natd gateway machine that was developing strange behaviour 
such that the
outside interface (ed0, BNC connector) that was connected via a small 
media converter switch to
the providers sync line had dropouts. The machine couldn't ping into the 
Internet and also couldn't be pinged.

I first thought it was the switch/media converter, but another (Windows 
XP) machine that was on the
same BNC cable worked flawlessly.

So I decided to migrate that 5.1 machine to a 9.0 machine. The situation 
now is that I have the9.0 machine
at the BNC cable and simultanously the old FreeBSD 5.1 gateway on the 
same BNC cable but through a
TP adapter. This was the old machine works fine and I can care about the 
new machine.

Is there a known problem with ed0 cards that have the Realtek 8029 
chipset. Do they need some
special flags like memory mapping or irq?

When I for example boot the 9.0 machine the comping up of the em0 (on 
mainboard interface results in a highlighted
kernel message on the console. The coming up of the ed0 is not flagged 
this way. And as a result the
ed0 interface seems to be dead.


Here some excerpts of dmesg:
em0: <Intel(R) PRO/1000 Network Connection 7.2.3> port 0x4400-0x441f mem 
0x93100000-0x9311ffff,0x93124000-0x93124fff irq 20 at device 25.0 on pci0
em0: Using an MSI interrupt
em0: Ethernet address: 00:1c:c0:37:b2:9f

ed0: <RealTek 8029> port 0x1000-0x101f irq 22 at device 1.0 on pci7
ed0: Ethernet address: 00:e0:7d:7c:2b:4a

I also see this:
Jul 30 23:03:54 forum ntpd[1711]: unable to create socket on ed0 (20) 
for fe80::
2e0:7dff:fe7c:2b4a#123

Help appreciated.
