Here's an updated pmap patch, which adds needed vm page queue locking to pmap_new_thread() ... this gets me to the mountroot prompt. However, something has changed in the last month, or I'm missing some patches or something, as I can no longer mount my root device. Geom? I don't know.. bootverbose doesn't seem to supply any useful info.
