Hi,
I'm running Fedora 28 in a Xen DomU on a Debian Stretch Dom0. This used to work fine but kernel 4.19.5 crashes on boot (see console output below) - 4.19.4 and earlier don't show any problems. Is anyone else seeing this? Is there a workaround?
Regards mks

I have no idea how this compares with
https://bugzilla.redhat.com/show_bug.cgi?id=1520265
but that was cured for me on an old HP box by a BIOS update.
The same box is now running 4.19.5 fc28

It looks like the "Linux 4.19.5 fails to boot as Xen dom0" issue being discussed on the xen-devel list, eg. see https://lists.xenproject.org/archives/html/xen-devel/2018-11/msg03557.html Basically there is an issue with the 4.19.5 kernel that upset Xen.

Thanks for the pointer! Guess, I'll try to rebuild the kernel with the patches posted there to see if that not only fixes booting as Dom0 but also as DomU.

Indeed, my DomU boots fine with an upstream 4.19.5 kernel with those patches applied.
