Kernel 3 comiling problem under XEN

Hello,

I`m running XEN 4.1.2 on OpenSuse 12.1 x64
I want to compile a new kernel (3.2.1) on SLES 11 SP1 in HVM mode.
It hangs on booting the new kernel. The root partition was not found.

Before booting the new kernel,
the command "mkinitrd -v -k vmlinux-3.2.1 -i initrd-3.2.1" gives somme error output:

Kernel image: /boot/vmlinux-3.2.1
