------- Comment #1 from alex@xxxxxxxxxxxx  2010-07-26 08:05 -------
I have the same bug, I have two passthrough  pci-devices into xen domains, one
it works fine, it wifi adapter, but network controller from realtek don't
working  after some updates in lenny, after upgrade to squeeze and xen4 this
bug still alive.

Here is my dom0 conf
