Subject4.7-rc3: Reported regressions from 4.7
Date
Hi! As announced last week in http://article.gmane.org/gmane.linux.kernel/2233992 
I'll try to write regression reports for 4.7. Find the first one below. Obviously
it looks a bit differently then those that Rafael wrote in the past. And I didn't
automatically send out mails to the persons involved. But well, you have to start
somewhere and it's better than nothing afaics. I'll manually send mails where I
think a poke is needed to get things rolling again (those contain a "todo-knurd:"
in the note as small reminder for myself).

Let me know if a regression in missing in the list. Or if there is something on the
list which shouldn't be there. Right now it contains 21 entries.

HTH, CU, knurd
