Hi Daniel, nice to "see" you again :-) Am 23.04.2011 11:09, schrieb Daniel Mack: > > Hmm, between these version, there was my huge refactoring of the > usb-audio code, so this could indeed be related.

I've sent a bisect log to the list some posts before. I've attached it to this mail again, in case you didn't see it. The last iteration would not result in a bootable kernel, so I've stopped there. (Actually I didn't stop there, but even guessing good/bad would not yield a bootable kernel in the next step). Kind regards, Felix
