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

Mon Nov 7 01:41:27 AEDT 2016

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

Ciao, Thorsten
