[Pkg-xen-devel] Bug#924360: xen-hypervisor-4.11-amd64: HVM Boot failure: "ERR: Bootloader shutdown EFI x64 boot services!"

[Henning]

Package: xen-hypervisor-4.11-amd64
Version: 4.11.1+26-g87f51bf366-3
Severity: important

Dear Maintainer,

   * What led up to the situation?

unfortunately xen hypervisor does not boot on my machine (Asus Prime B360M-C Mainboard, in Setup only EFI enabled, Intel VMX Virtalization Technology is enabled, too). Installation was done according to https://wiki.debian.org/Xen .

With a serial connection, I get the boot messages (the last line is not visible on the HDMI screen):

Loading Xen 4.11-amd64 ...
Loading Linux 4.19.0-2-amd64 ...
Loading initial ramdisk ...
error: no suitable video mode found.
ERR: Bootloader shutdown EFI x64 boot services!

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   * What was the outcome of this action?

"Normal" Linux (intended as dom0) boots perfectly.
By providing load_video on grub2 commandline I do not have the line "error: no suitable video mode found." any more. However, the last error line stays the same and only reset is possible.
After installing stable first I tried to upgrade/dist-upgrade to testing but the problem stays the same.
I already tried to find something with Google related to the error but could not find anything.

Kind regards,
Henning
