[Xen-devel] [xen-4.13.0-rc] kexec/kdump failure with cpu Intel(R) Xeon(R) Gold 6242 CPU

[Dietmar Hahn <dietmar.hahn@xxxxxxxxxxxxxx>]

Hi,

on a new machine with cpu Intel(R) Xeon(R) Gold 6242 CPU the kexec/kdump
doesn't work with current xen-4.13.0-rc.
The last output of the xen console is:

(XEN) Hardware Dom0 crashed: Executing kexec image on cpu5
(XEN) Shot down all CPUs

After short delay the system reboots.

It seems the fixes mentioned in the thread
https://lists.xenproject.org/archives/html/xen-devel/2019-10/msg01948.html
aren't enough.

I built xen-4.11 with the patches but no success.
On an older system with xen-4.4 the kdump works.

Any help is appreciated.
Thanks.

Dietmar.
