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

Mon Oct 31 00:20:25 AEDT 2016

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 at leemhuis.info). And please tell me if there
is anything in the report that shouldn't be there.

Ciao, Thorsten
