Very large and famous (due to very attractive prices) hosting

additional money) only under FreeBSD. Linux works fine.
Switches known to be Juniper e3k series.
MoBos of servers are different assortment of MSI MoBos with Realtek
(re driver) network-on-board.
Symptjms are: NIC can not negotiate/set duplex when switch port is
limited to 100Mbit/Duplex. Duplex can not be set even manually via
"ifconfig":
media: Ethernet 100baseTX <full-duplex> (100baseTX <half-duplex>)
Is it know problem? Maybe, -CURRENT driver has fix for it?
Unfortunately, I can not provide more information, as I don't have
server at Hetzner (I'm planning to order one, but due to these
problems, I'm not sure now, as I need FreeBSD), and all this
information is collected in communication with people who HAVE servers
with FreeBSD installed.
Hi,
I've got several Hetzner EQ4 and on all these machines FreeBSD 8.1 runs
just fine. I've never seen this strange negotiation problem myself. But
maybe I was just lucky and got working mainboard and nic combinations.
So if further information is needed, I'm happy to provide it.

Also have a look at the FreeBSD section in the Hetzner Wiki:
http://wiki.hetzner.de/index.php/FreeBSD
It's in german but Google can translate it :)
Ciao,
