I use this box mostly w/amd64 -current. I boot in i386 appx. weekly to do a
partial dpb bulk build. I don't use tmpfs (or mfs) in i386 mode. I do the dpb
builds (both i386 and amd64) w/ chroot. This is the first time I've
encountered this problem. Let me know if I can help further.
FWIW, here's some further info:
