It seems like the automatic bisection job on staging.kernelci.org
found what might have caused this failure. It's still an
experimental tool but hopefully it will eventually be useful and
save time when looking for the root cause of boot failures...
Here's what it found:
commit 7313cfa4f6e30384fa04083698d1e865cf812a6a
Author: Ben Skeggs <bskeggs@xxxxxxxxxx>
Date: Wed Nov 1 03:56:19 2017 +1000
drm/nouveau/bar: move bar1 initialisation into its own function
BAR2 being done for practical reasons, this is just for consistency.
Flushes have been added after the write to bind the instance block,
as later commits will reveal the need for them.

Kernel error:
[ 2.402977] nouveau 57000000.gpu: gr: failed to load fuc409c
[ 2.456166] Unable to handle kernel NULL pointer dereference at virtual address 00000000
It looks like the same DRM driver issue that was found previously
on linux-next (CC Jon Hunter). I would be interested to know if
this is actually the commit that introduced the problem, hoping
it can help getting it fixed but also to collect results from the
new bisection tool. It would be great if you could please let me
know if you find out, and apologies if it isn't.

Hope this helps!
