Linux 4.13: Reported regressions as of Sunday, 2017-09-03

[Thorsten Leemhuis]

Hi! Find below my fifth regression report for Linux 4.13. It lists 4
regressions I'm currently aware of. There are no new ones; 2 got fixed
since the last report.

You can also find the report at http://bit.ly/lnxregrep413 where I try
to update it every now and then.

As always: Are you aware of any other regressions? Then please let me
know. For details see http://bit.ly/lnxregtrackid 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, it makes compiling these reports a whole lot easier!
