Linux 4.9: Reported regressions as of Sunday, 2016-10-30

[Thorsten Leemhuis]

Hi! Here is my second regression report for Linux 4.9. It lists 14
regressions I'm aware of. 4 of them are new; 3 got fixed since last weeks report.

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

Ciao, Thorsten
