This looks oddly similiar to my problem to which I haven't found solution so
far. I'm using NetBSD domU guest on Citrix Xenserver and after applying some
patches to it all PV guests stops boot anymore.

This may be because you need

on the Xen boot command line.

Does this apply to Xen 4.6.5 as well?

it depends if it got the security patch which disables it or not
(XSA240, from memory)

I tried starting the same NetBSD guest on a different server with Xen
4.6.5 with the same result.  I was going to try

# xen-cmdline --set-xen pv-linear-pt=true

but I don't have xen-cmdline on my servers.

xen-cmdline is part of XenServer (xapi stack), it won't be on a vanilla Linux dom0.
