I have some diagnostic Info for you. Tried to get xen-4.0.1 working on
another node of my cluster. Only difference: Newer revision of the
Hardware. Exactly same Software Stack.

Stack: Ubuntu Lucid 64bit, xen-4.0.1 from Source, selfbuilt
linux- from xen/stable-2.6.32.x

Nodes working: HP DL380G5 16GB (Intel X5460)

Node not working: HP DL380G6 16GB (Intel X5550)

Effect: Xen starts but dom0 Crashes immidiately after I see the message
"Scrubbing free Ram". I attached Screenshot of the Management Processors
Serial Port.

I used the same dom0 kernel deb that successfully runs on other Nodes
(as well on xen-4.0.1).

Any ideas? I'm really stuck on this. I use XEN since 5+ years, but I
never had that one..
