--- Comment #29 from Michel Dänzer michel@daenzer.net --- (In reply to Alexandre Demers from comment #27)
I'm trying to figure out a way to distinguish one from the other because from where I am in the bisection, I was unable to reproduce the bug with a 3.16 kernel, but it does appear before 3.17-rc1...
That's fine. Once you've finished bisecting the kernel, we'll decide where to go from there based on the result.
