Linux 4.11: Reported regressions as of Sunday, 2017-04-09

[Thorsten Leemhuis]

Hi! Find below my third regression report for Linux 4.11. It lists 15
regressions I'm currently aware of. 5 regressions mentioned in last
weeks report got fixed.

As always: Are you aware of any other regressions? Then please let me
know (simply CC regressions@leemhuis.info). 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 or provided
other input, as that makes compiling these reports a whole lot easier!

Note, Andrea saw a completely different problem unrelated to the GPU
hang and date back to ~4.9. Both reported issues have been fixed, with
the earlier report already in mainline but Andrea's fix is not yet in a
PR.
