I don't see rm_alloc_agp_pages anywhere in the open part of the source code. I just looked again... I see the function prototype in nv.h, but that's it. screwdriver:~/dl_temp/NVIDIA_FreeBSD-1.0-3203:> grep -R rm_alloc_agp_pages * Binary file obj/Module-nvkernel matches src/nvidia_subr.c: if (rm_alloc_agp_pages(nv, address, count, class, private, src/nvidia_subr.c: if (rm_alloc_agp_pages(nv, address, count, class, private, src/nv.h:RM_STATUS rm_alloc_agp_pages (nv_state_t *, VOID **, U032, U032, VOID **, U032 *); so from what I can tell, it IS in the proprietary part of the driver. > It'd be interesting to learn if the code path you suspect really is > the one taken in the case of this failure.
