When you say you built a debug kernel, does that include option
WITNESS_KDB? If so, remove that so you can find the real error. LORs
related to ufs_dirhash have been reported for years, and nobody with the
appropriate skills seems to be interested in fixing them; they just get
declared to be harmless. (IMO the spewage related to this makes witness
essentially useless.)
