--- Comment #5 from Joaquín Aramendía samsagax@gmail.com --- Created attachment 159291 --> https://bugzilla.kernel.org/attachment.cgi?id=159291&action=edit fix for runtime power management in nouveau

I made this patch that fixed the issue for me. Applies on top of commit a4c5f39. Should apply with offset to newer kernels but fine.
