I'm trying to run Xen 4.0.1 with Debian Squeeze in Dom0
My grub config:
menuentry 'Debian GNU/Linux, with Linux 2.6.32-5-xen-amd64 and XEN 4.0-amd64' --class debian --class gnu-linux --class gnu --class os --class xen {
insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set e719719a-35aa-4ada-8ab5-9b6c676bc89e
echo 'Loading Linux 2.6.32-5-xen-amd64 ...'
multiboot /boot/xen-4.0-amd64.gz placeholder iommu=off
module /boot/vmlinuz-2.6.32-5-xen-amd64 placeholder root=UUID=e719719a-35aa-4ada-8ab5-9b6c676bc89e ro  quiet
echo 'Loading initial ramdisk ...'
module /boot/initrd.img-2.6.32-5-xen-amd64

After boot i see in console:
Failed to execute /init
Kernel panic - not syncing: No init found. Try passing init= option to kernel
Pid: 1, comm: swapper Not tained 2.6.32-5-xen-amd64 #1

Initramfs unpacking failed: junk in compressed archve
registering netback
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Kernel vmlinuz-2.6.32-5-xen-amd64 without xen boots normaly.

My "trouble" server is IBM HS-22 (2x Xeon E5530, 36 GB RAM, LSI SAS).
The same configuration works correctrly on other machine (supermicro-based).
But this is not "bad hardware" trouble - i tried two different HS-22
