As far as I know, this is the first report of the problem on a STABLE system (if it's the same problem). Try building a new kernel without APM (and don't load it in /boot/loader.conf, either). If this allows the system to boot, please submit a PR so that the few people who understand the locore.s stuff well enough to have a chance to find it can get it fixed.
