Linux 4.9: Reported regressions as of Sunday, 2016-11-06

[Thorsten Leemhuis]

Hi! Here is my third regression report for Linux 4.9. It lists 17
regressions I'm aware of. 6 of them are new; 3 got fixed since
last weeks report (a fourth looks fixed as well). The console
problem ("console: don't prefer first registered [...]") got
reported to me multiple times, but the revert to finally get
this fixed is in -mm already.

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
