--- Comment #2 from Patrice Mandin 2011-05-23 02:11:14 PDT ---
In nouveau_card_init() function (nouveau_state.c file), engine->fifo.init()
function is not called when nouveau_noaccel is enabled.
On NV50/NVA0 cards, engine->fifo.init = nv50_fifo_init (nv50_fifo.c file) and
this function is responsible to fill pfifo->playlist array, which is not done
with nouveau_noaccel enabled.
When nv50_fifo_playlist_update() is called, accessing pfifo->playlist (which
was not initialized) triggers the NULL pointer dereference.
