Linux 4.8: Reported regressions as of Sunday, 2016-08-14

[Thorsten Leemhuis]

Hi! Here is my first regression report for Linux 4.8. It lists 11
regressions. I was told or found about 10 more, but it turned out all 
of them were fixed already in the past few days. Nice, but this in one 
of the reasons why compiling this report took way more hours than the 
past few reports :-/

Anyway: Are you aware of any other regressions? Then please let me 
know. And you know the drill: if there is anything on the report that 
shouldn't be there please let me know.

Ciao, Thorsten

P.S.: Gmane, I still miss you a lot :-/

P.P.S.: "There are only two hard things in Computer Science: cache 
invalidation, naming things, and off-by-one errors" is my reply to 
those that asked to lend my time machine after reading the line "I'll
send the first regression report for 4.9 next week" that last weeks
report contained ;-)
