[Xen-users] Xen 3.2.0 on debian etch, many kernel panics

[Jordi Moles <jordi@xxxxxxxxx>]

Hi,

i'm trying xen 3.2.0 on debian etch. I installed everything from the 
repositories.
I added the lenny repositories so that i could install the lastest 
packages and have xen 3.2.0 on my machine from the debian repositories.
these are the packages installed:

ii  linux-image-2.6.18-6-xen-amd64    
2.6.18.dfsg.1-18etch1                Linux 2.6.18 image on AMD64
ii  linux-modules-2.6.18-6-xen-amd64  
2.6.18.dfsg.1-18etch1                Linux 2.6.18 modules on AMD64
ii  xen-hypervisor-3.2-1-amd64        
3.2.0-2                              The Xen Hypervisor on AMD64
ii  xen-tools                         
3.9-2                                Tools to manage Debian XEN virtual 
servers
ii  xen-utils-3.2-1                   
3.2.0-2                              XEN administrative tools
ii  xen-utils-common                  
3.1.0-1                              XEN administrative tools - common files
Everything was installed without any trouble or warning or error 
reported in the logs, but now... well... the whole machine keeps hanging 
with kernel panics.
This is an example:

************************

This actually happens in several new machines i'm testing. I've run disk 
and memory tests on them and no problem reported at all.
They are intel quad core, 8 virtual cpus.

Do you have any idea where my problem is?

Thank you.
