This is not a panic.

 786 void vc4_plane_async_set_fb(struct drm_plane *plane, struct 
drm_framebuffer *fb)
 787 {
 788         struct vc4_plane_state *vc4_state = 
to_vc4_plane_state(plane->state);
 789         struct drm_gem_cma_object *bo = drm_fb_cma_get_gem_obj(fb, 0);
 790         uint32_t addr;
 791
 792         /* We're skipping the address adjustment for negative origin,
 793          * because this is only called on the primary plane.
 794          */
 795         WARN_ON_ONCE(plane->state->crtc_x < 0 || plane->state->crtc_y < 0);
 796         addr = bo->paddr + fb->offsets[0];

Whatever it is, it should not be fatal.
