Hi! Here is my fifth regression report for Linux 4.8. It lists 15 regressions I'm aware of. 5 of them are new (for many of those there are patches available to fix the regression); 3 mentioned in last weeks report got fixed; 1 is going to be removed.
As always: Are you aware of any other regressions? Then please let me know (simply CC regressi...@leemhuis.info). And please tell me if there is anything in the report that shouldn't be there.
