[Pkg-xen-devel] Bug#903821: xen-hypervisor-4.8-amd64: Kernel Panic after upgrading to stretch 9.5 (linux-image-4.9.0-7-amd64)

Package: xen-hypervisor-4.8-amd64
Version: 4.8.3+xsa267+shim4.10.1+xsa267-1+deb9u9
Severity: critical
Justification: breaks the whole system

Dear Maintainer,

After updating 3 Xen servers from stretch (9.4) to stretch (9.5), I notice
a kernel panic on these 3 servers.

If I boot xen hypervisor with advanced option in grub menu, and If i select
linux-image-4.9.0-6-amd64 kernel, everything work.

The 3 servers are from Dell :

- 1 PowerEdge R720
- 2 PowerEdge R430

You can find the message displayed on IDRAC console when booting with
4.9.0-7-amd64 :

Call Trace:

 ---[ end trace 28169cf87e381c4e ]---
 Kernel panci - not syncing: Attempted to kill init! exicode=0x0000000b
 Kernel Offset: disabled

 After this, the servers reboot in loop.

 If you need any others informations, please let me know.

 Best regards.

 Benoît
