Hi list,
I'm trying to get xen-unstable working on a dual opteron.
My dom0 is a debian-amd64 testing release, and it is working fine!
But I'm unable to boot my domU. I also istalled a debian-amd64 on this one. Every time the kernel tries to mount the root partition it panics:

I also tried to compile my own xenU kernel (i hav gcc 4.0). The FS of my xenU image ist ext3. Even with an initrd.img it was not mountable.
Some time ago i installed an xen 2 Server without problems, but i have no ideas left where the problem might be.
Does anyone of you have a solution or even a hint?
Thanx in advance,
Jan
