Hi! Here is my eight regression report for Linux 4.7. It lists 13
regressions I'm currently aware of. 6 of them are new; none were fixed.

As usual: Please let me know about any regressions missing on the list
or if it contains something which shouldn't be there. Since the release
of 4.7 there were quite a few new bugs filed on
that mentioned 4.7; I briefly looked at them, but it looks like most of
them are not regressions.

Ciao, Thorsten
