Subject: Linux 4.14: Reported regressions as of Sunday, 2017-10-08

Hi! Find below my second regression report for Linux 4.14. It lists 8
regressions I'm currently aware of. One regression was fixed since last
weeks report. One was in there that shouldn't have been there.

As always: Are you aware of any other regressions? Then please let me
know by mail (a simple bounce in my direction is enough!). 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 Adam and Igor for pointing me at two regressions they face.
And thx to Yanko for pointing out a stupidity I did in last weeks report.
