This looks suspiciously like the issue which was fixed by c/s
d6b186c1e2d852a92c43f090d0d8fad4704d51ef "x86/xen: avoid m2p lookup when
setting early page table entries", but that fix is present in Linux 4.7.0
Can you check to see whether the commit is included in your kernel?
Failing that, can you find out exactly where the kernel crashed? You
need to manually decode ffffffff81f6374c with the debug symbols.
