I have reported this here, too:

https://lists.freebsd.org/pipermail/freebsd-xen/2017-August/003079.html

I think it is needed for some newer Linux kernels only.

I am successfully using Windows, Solaris and some other wierd HVM
guests without this option successfully. xen_platform_pci=1
seems to confuse Linux 4.* line (2.6.32 boots fine).
