Reported it at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=852324 but
given Ben Hutchings' reaction it seems to be a Xen problem after all.
Relevant part of earlier attached dmesg:
[ 13.588386] WARNING: CPU: 18 PID: 1 at /build/linux-zDY19G/linux-4.8.15/arch/x86/mm/dump_pagetables.c:225 note_page+0x5e8/0x790
