Summa summarum

With the above mentioned drm-next kernels at least works boot from soft-off(S5).
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?

Oh yeah!
With 3.18.0-0.rc1.git0.1.fc22.x86_64 even the magic SysRq key sequence is
