ok, I tried from "Linux 2.6 (for supported distros)".
The mkfs.ext3 advanced a little bit further than before, but still I got
my kernel dump. :-|
Moreover I've got a warning about a 'struct device_driver shutdown method'.

Any more hints?
Would there be another approach, e.g. to apply somehow the xen patches
to the centos / upstream kernel and use that one?
