Do either of you have the CVS tree so that you can walk backward through
the revisions and determine exactly where this broke? The -current branch
has better granularity so it would be best to do it from there. I cannot
reproduce this behavior on my hardware, so I've resorted to an inspection
of all changes since April 1. Narrowing this down to one revision would
greatly help me to find the problem.

This is to be expected. You only have 16 SCBs. The older driver had a bug.
