12.2-STABLE r369477 dom0 creash on xen-kernel-4.14.1_1

[Roger Pau Monné via freebsd-xen]

Hello,
I have just upgrade my machine that used to ran 11.x with Xen 4.7.2_9
as dom0 for a long time.
After upgrade to 12.2-STABLE r369477, runs GENERIC kernel just fine.
Unfortunately it crashes as Xen dom0 with xen-kernel-4.14.1_1

Do you have dom0=pvh set on the Xen command line? Note 4.7 used
dom0pvh=1 instead [0], so you will have to modify your loader.conf.

Thanks, Roger.

Thank you - that was it!

I read this article but this difference escaped my attention.
I have only removed "hw.pci.mcfg=0".

Now it works fine again, big thanks for keeping Xen so well supported on FreeBSD!
