Xen users - Feb 2006 - Xen 3.0.1: network doesn''t work

I just compiled 3.0.1 from sources (make world; make install) and
booted it. The subject sais it all. The network doesn''t work. At all.

My testing box is an AMD Sempron 2600+ on an Asus A7V880 motherboard.
It has an integrated gigabit ethernet (sk98lin driver) and an Intel
E1000 Pro/MT.

When I boot dom0, the network drivers are loaded and the interfaces
are recognised and initialized. I can configure both eth0 and eth1
using ifconfig, but I can''t get them to actually communicate
anything.

I pulled 2.6.15-xen from linux-2.6-xen.hg and with that I get
networking in dom0. However, as a domU it can''t find any VBDs and
thus won''t boot. 2.6.12.6-xenU will boot, but the network is really
broken.
>From within the domU, I can ping other hosts on the network, but TCP
connections seem to fail (eg. trying to log into the domU via SSH).

I figured this one out:

Compiling CONFIG_BLK_DEV_SD statically into the domU kernel makes Xen
not able to find virtual disks. Is this a bug?

Looks like my networking problem is a known bug:

Running "ethtool -K eth0 tx off" inside a domU will make the network
work just fine.
