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 [ 13.588388] x86/mm: Found insecure W+X mapping at address ffff880000000000/0xffff880000000000 ... [ 13.608867] x86/mm: Checked W+X mappings: FAILED, 4602 W+X pages found.
