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.
