After 2fb9d6cf (drm/nouveau/core: convert event handler apis to split
create/enable semantics) from the nouveau tree I'm getting a kernel
panic on boot because pdisp is 0 at core/engine/software/nv50.c:179.
The nouveau part of the call trace is:
nv50_software_context_ctor+0x80/0x130
nouveau_object_ctor+0x2d/0xe0
nouveau_object_new+0xfa/0x230
nouveau_channel_new+0x53b/0x6c0
nouveau_drm_load+0x436/0x6c0
...
nouveau_drm_probe+0x202/0x290
...
nouveau_drm_init+0x43/0x1000
Is there anything else you need?
Martin
