   I'm having similar problems w/o even trying to use an initrd.  I did
a fresh clone of xen-ia64-unstable.hg (newer xlilo patch already
included) and ran make.  Previously I was using xlilo.efi as if it were
elilo.efi (ie. image=xen initrd=xenlinux).  Yes, this is now broken.
Switched to image=xenlinux and vmm=xen.gz and it works, until...

Detecting hardware...(XEN) handle_op: can't handle privop at 0xa000000000010650 
(op=0x0000000008000000) slot 0 (type=1), ipsr=0000101208026038
(XEN) priv_emulate: priv_handle_op fails, isr=0000000000000010
discover[1158]: General Exception: IA-64 Privileged Operation fault 16 [1]

discover is the one that starts the string of core dumps for me and it claims:

ip is at __kernel_syscall_via_epc+0x10/0xc0

Looks like something is busted in the tree.  Thanks,

        Alex
