kristof, olivier,

thank you for writing back (:

I was also unable to reproduce my steps running a 11.1-RC3 guest here on my
workstation with bhyve, qemu or even virtualbox. my host OS is a FreeBSD
12.0-CURRENT/amd64 (r320640, 1200037).

the "main" hypervisor I did use that presented me with a kernel panic is a
linux-based OS with kvm; proxmox 5.0-23/af4267bf (debian 6.3.0-18, kernel
4.10.15-1-pve).

I did build a DEBUG kernel and just tested it; 11.1-PRERELEASE (r320976+)
worked just fine. the sad thing is that I completely forgot to remove pf from
the KERNCONF after adding the DEBUG options. so, I'm rebuilding it again and
will test it again - following the very same procedures I reported before.

olivier,

the reason I am using loader.conf is: when one uses the rc.conf the rc.d/pf
script doesn't load the module if there's no pf.conf available, or it loads the
module quite "late". so, I was just being sure that pf.ko would be loaded no
matter what.
