I think we're talking about different issues here.

I can was able to reproduce the problem on
-FreeBSD 5.0-RELEASE
-FreeBSD 5.1-RELEASE
-FreeBSD CURRENT (today)
-NetBSD 1.6.1

However it does does not occur on
-FreeBSD 4.3-RELEASE up to 4.8
-FreeBSD STABLE (today)

Thus I assume the problem lies within the bktr-driver since it
also occurs on NetBSD and it must be something which has been
changed in -CURRENT before 5.0-RELEASE and not MFC'ed yet because
todays -STABLE still works fine.
Does anyone have a slight suspicion what change might cause the
above-mentioned problem?
