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.) -- Ian _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
