Subject: Linux 4.11: Reported regressions as of Tuesday, 2017-04-02

Hi! Find below my second regression report for Linux 4.11. It lists 13
regressions I'm currently aware of. It lists 6 fixed regressions. Some
of them where in the first report from three weeks ago; a few were 
supposed to go into a second report I prepared last week, but wasn't 
able to finish :-/

As always: Are you aware of any other regressions? Then please let me
know (simply CC And please tell me if there
is anything in the report that shouldn't be there.

Ciao, Thorsten

P.S.: Thx to all those that CCed me on regression reports, that makes
compiling these reports a whole lot easier!
