However broken are resume from suspend(S3) & hibernate(S4). The above mentioned Fedora kernels including 3.18.0-0.rc1.git0.1.fc22.x86_64, based on linux-next & derivatives, all broke boot from soft-off(S5) - after "fb: switching to nouveaufb from VESA VGA" you can only get WhoTF turned out the lights! What the circus. What is the best, I've compared the last working kernel and first broken, guess what, no diff within gpu/drm/nouveau/ branch. BTW (kernel_hibernate) Hibernation issue tracker bug https://bugzilla.redhat.com/show_bug.cgi?id=781749 Are you really such opportunists? poma
