Hello,
I've been able to debug this and found the issue. I have two patches that
should be applied to FreeBSD in order to fix it, they can be found at:
https://people.freebsd.org/~royger/privcmd_fixes/
Could you please give them a try?
I have however been unable to boot a Solaris 11.3 guest under PV mode, but
at least the host is not crashing anymore :).
Roger.
