On a amd64 domU with 4 CPUs I see under high load:
xpq_flush_queue: 1 entries (0 successful)
0x0000000220a58010: 0x000000014d121067

And on xen console:
(XEN) mm.c:2424:d1 Bad type (saw 3400000000000001 != exp 7000000000000000) for

000000020e43d067 for l1e_owner=1, pg_owner=1

I don't know yet if it's related to kern/45830
