Linux 4.13: Reported regressions as of Sunday, 2017-08-06

Hi! Find below my second regression report for Linux 4.13. It lists 10
regressions I'm currently aware of (albeit in one case it's not entirely
clear yet if it's a regression in 4.13). One regression got fixed since
last weeks report. You can also find the report at 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 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!
