<pre>Looks like you have no outputs. I think this will lead to
chan->vblank.nr_event = pdisp->vblank->index_nr;
failing in nv50_software_context_ctor, called from nouveau_accel_init since
pdisp->vblank == NULL. I suspect that ->index_nr is at offset 0x130 which
explains the CR2 that you see.
As a temporary workaround, booting with nouveau.noaccel=1 will avoid the crash
(and also remove your ability to use the card).</pre>
