I see next trivial (but interesting to me) differences in same case:

Older (good) kernels show messages on boot: [ 0.898887] [drm] nouveau 0000:00:0d.0: ======= misaligned reg 0x0060081D ======= [ 0.898919] [drm] nouveau 0000:00:0d.0: ======= misaligned reg 0x0060081D =======

That's a separate issue and has nothing to do with this bug. See https://bugs.freedesktop.org/show_bug.cgi?id=47182 In most cases, it is no bug at all.
