--- Comment #12 from Matteo Bruni matteo.mystral@gmail.com --- (In reply to alex freudenberg from comment #3)
The issue occurs from kernel 4.8.3-1-ARCH onwards. Last working kernel version is 4.8.2-1-ARCH.
It would be nice if someone wants to give a shot at bisecting the kernel between 4.8.2 and 4.8.3 to find the commit which broke it. You need to be able and willing to build your own kernel but it's not too complicated, if a bit distro-dependent. There are a number of guides on the web which should help with that.
