That sucks, I don't want to lose DRM if I multiboot between kernels that
have 4.1.x and 4.0.x. Somehow I doubt running both versions is easy or
reasonable. I wonder if NVidia has its DRM out yet for 4.1.x (I guess
SGI is a big participant in DRM area).

I've heard there are difficulties in having a kernel that simultaneously
supports both DRM models, though part of it is a matter of naming. I
certainly can't upgrade to any kernel that doesn't have 4.0.x DRM
ability (at least not if NVidia drivers are not available). Since I'm
using XFS, whatever I use has to be XFS as well.
