Synopsis: uhmodem(4) hotplug chashes on amd64

Responsible-Changed-From-To: port-amd64-maintainer->kern-bug-people
Responsible-Changed-By: tnn%NetBSD.org@localhost
Responsible-Changed-When: Wed, 22 Apr 2009 07:21:49 +0000
Responsible-Changed-Why:
I can reproduce the problem on i386.
I have some crude workaround patches that insert sleeps in
various places; it looks like timing matters (locking problem?).
Will attach patches to PR in case they help anyone debug it.
