I'm off on vacation next week, so I don't have much more time for this.
There are a couple more issues that I want to look at before I go, so
any such analysis on my part will have to wait.  The file is attached
to PR10062 and according to Albert the problem is present on all ports
to one degree or another.  For some reason, the problem seems worst
on the PA.

Yes.
