HTT isn't expected to cause problems at least on modern versions of
FreeBSD (I dont remember if old versions like 5.4 have a bug), but it
could be if you are running older hardware with broken BIOS support.

You definitely need to drop to single-user mode and fsck -f:
filesystem corruption can cause many problems.

will probably involve an upgrade to a newer version as a first step.
