I retried 15165 + test.patch (including your patch).
I had the only following message while a booting of domU.
But if I do shutdown on the domU, then Hypervisor doesn't panic.
The following backtraces include __do_dom0vp_add_physmap(),
Is that OK?

The backtrace seems to be happend at xen_ia64_dom_fw_map() for boot_param.
111 int
112 xen_ia64_dom_fw_setup(struct xc_dom_image *d, uint64_t brkimm,
113 unsigned long bp_mpa, unsigned long maxmem)
114 {
[snip..]
147 /* Create page for boot_param. */
148 bp = xen_ia64_dom_fw_map(d, bp_mpa); <<<<<HERE
149 if (bp == NULL) {
150 rc = -errno;
151 goto out;
152 }
153 rc = dom_fw_init(d, brkimm, bp, imva_tables_base,
154 (unsigned long)imva_hypercall_base, maxmem);
[snip...]
165
166 return rc;
167 }
