Hi,

As also seen at:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=914951

Attached there are two serial console output logs. One is starting with
Xen 4.11 (from debian unstable) as dom0, and the other one without Xen.

[    2.085543] BUG: unable to handle kernel paging request at
ffff888d9fffc000
[    2.085610] PGD 200c067 P4D 200c067 PUD 0

[    2.085823] Hardware name: HP ProLiant DL360 G7, BIOS P68 05/21/2018
[    2.085895] RIP: e030:ptdump_walk_pgd_level_core+0x1fd/0x490
[...]

The pti=off setting on the PV dom0 kernel is left behind from the time
when 4.9 failed to boot as Xen dom0 because of the bug handling that.

Hans
