Hello,
I tested xen 4.11.0 rc1 with NetBSD as dom0.
I could boot a NetBSD PV domU without problem, but at shutdown time (poweroff
in the domU), I got a Xen panic:
(XEN) Assertion 'cpu < nr_cpu_ids' failed at
...1/work/xen-4.11.0-rc1/xen/include/xen/cpumask.h:97
A xl destroy instead of poweroff gives the same result.
This happens with both 32bitsPAE and 64bits domU. This doens't seem to
happen with HVM domUs.
Attached are a cut-n-paste of the panic, and the output of xl demsg.

(XEN) WARNING: CONSOLE OUTPUT IS SYNCHRONOUS
(XEN) This option is intended to aid debugging of Xen by ensuring
(XEN) that all output is synchronously delivered on the serial line.
(XEN) However it can introduce SIGNIFICANT latencies and affect
(XEN) timekeeping. It is NOT recommended for production use!
