Kenji, I have had similar problems booting terminals from remote fileservers and even when loading drawterm on a computer connected to the CPU/auth/file server by a single switch. In the latter case, at least, my problem seems to have been related to a misconfigured /lib/ndb/local. Anticipating a forthcoming network change, I had used the server's as-yet-unconfigured domain name in /lib/ndb/local in various dom= and auth= fields. As some people have speculated, this seems to cause an attempted DNS lookup somewhere along the line, but since that name doesn't resolve to the correct machine, you end up waiting a long time. Changing "plan9.domain" to just "plan9" in the auth= and dom= fields for my network and server entries seems to have cleared up the problem.
