Hi, Robert,

thank you very much for your reply!

You are welcome!
Well, as stated in the reports, I'm prepared to help with additional
information and tests I can provide.

My main background is Gentoo (GNU/Linux source based rolling meta-
distribution), thus knowing my way around building my hand-crafted
kernels ...

Kind regards
Manfred
