The FBIOPUT_CON2FBMAP ioctl takes a console_lock(). When this is called while nouveau was runtime suspended, a deadlock would occur due to nouveau_fbcon_set_suspend also trying to obtain console_lock(). Fix this by delaying the drm_fb_helper_set_suspend call. Based on the i915 code (which was done for performance reasons though). Cc: Chris Wilson <chris at chris-wilson.co.uk> Cc: Daniel
