That's weird. I have the same basic /boot/loader.conf entries (except for a
speed of 115200) and even just putting "-Dh" into /boot.config leads to the
same unbootable system behaviour. :-(
Maybe something broke recently in the RELENG_8 boot loader? Like I said
originally, that /boot.config entry had been working for me without problems
for a long time.
Cheers,
