Kelly, the /boot/loader.conf file does not come into play at that stage. Early in the loader code, loader needs to figure out, which disk (BIOS device) has been booted from. Until loader knows which device was booted up, it's unable to access any files (even loader.conf) on your boot device. As I've never seen such a problem while upgrading any system, I suspect your problem must be settings specific. Can you show me your kernel config or are you using a plain vanilla GENERIC? Which arch are we talking about? As I'm currently investigating another boot problem (but earlier in the boot chain), I'll check boot logic in the source code and may check for your issue, too, at that time, so it's just one effort. But please stay patient for some days, as I'm currently too busy. Volker
