Hi! Here is my fourth regression report for Linux 4.7; a day earlier then usual. It has 14 entries; * 2 of them are new * 9 regressions (not included here) were fixed since the last report(¹) * 1 made it to the list after last Sunday (thx for telling me about it Kalle!), but was fixed before I compiled this one * 2 turned out to not be regressions at all * 1 was a duplicate
Fixes for 4 of the regression in this report are heading towards mainline. One of the remaining regressions is likely fixed already. Please let me know if a regression is missing in the list; or if there is something on the list which shouldn't be there.
