Description Arik Raffael Funke 2007-07-18 19:45:05 EDT
Description of problem:
Adsl connection that works flawlessly on a system started with a non-xen kernel 
ceases to work when system is started with xen-kernel as dom0. The system is 
CLEAN and there are NO configuration/environment changes between the two 
situations EXCEPT the choice of the kernel during grub-stage.

Steps to Reproduce:
1. Clean install of Fedora 7 with virtualisation option
2. Start with non-xen kernel and setup adsl (i.e. connect to a adsl modem via a 
network card). This works flawlessly.
3. Restart with xen-kernel into dom0
4. Retry to connect with adsl: impossible


Demonstration:

In non-xen kernel: (adsl works)
===============================
[root@gaia ~]# pppoe -I eth0 -A
Access-Concentrator: ULMC03-10k
Got a cookie: ea 64 c2 d8 c9 f6 70 96 72 27 c2 72 eb 23 fb 1d
AC-Ethernet-Address: 00:19:e8:6e:70:31
--------------------------------------------------
[root@gaia ~]#


In xen-kernel, dom0: (adsl does not work)
=========================================
[root@gaia ~]# pppoe -I eth0 -A
pppoe: Timeout waiting for PADO packets
[root@gaia ~]# 



In /var/messages it says (in dom0 where adsl connection fails):
