Try to boot into single-user mode, i.e., when the system boots, it'll display
a 10 second countdown. Hit spacebar to abort the countdown. Then type boot
-s and it'll boot into single-user mode with only the root partition mounted.
type mount -a to get the other partitions mounted.
Then redo your buildworld,etc., but skip mergemaster stuff.
Here's the steps:
make buildkernel KERNCONF=yourkernelname (you DID copy GENERIC and customize
it didn't you?)
make installkernel KERNCONF=yourkernelname
Skipping the mergemaster stuff will mean that any recent changes to various
config files will be missing, but you should be able to come up multi-user.
If these steps fail, it'll probably be easier to just reinstall.
