This is my primary workstation, which is not very convenient to test with
at this time (I lost 3 hours of work already getting it stabilized again).
Could you perhaps use my config on one of your test systems and try to
duplicate first?  If you can not duplicate, I will be willing to put some
more effort into testing on my end.

Thanks,
