Since next upload seems to be targeted at unstable, we should have this fix already: https://salsa.debian.org/kernel-team/linux/merge_requests/82 Hans

Copy at https://lists.xenproject.org/archives/html/xen-devel/2018-11/msg03313.html But at least if someone else would also report or search for it, we have this one to point to. :) > Attached are two serial console output logs.

However, the full attached log is from 4.19.5-1~exp1 which fails in exactly the same way. > [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 van Kranenburg
