<pre>drm-next appears to be hitting this logic in nv50_disp_chan_ctor:
if (disp->chan[chan->chid.user]) {
chan->chid.user = -1;
return -EBUSY;
}
when constructing the cursor for head 1.
drm/nouveau/nvkm/engine/disp/nv50.h: struct nv50_disp_chan *chan[17];
Oops. That should be [21]. It was reading/writing random memory :(</pre>
