Problem 4363 building kernel modul (2.4.20 SMP HIGHMEM)
 
On my system the nvidia installer (4363) tries to built a kernel module but this has unresolved symbols. Excerpt from my /var/log/nvidia-installer.log:

Kernel module load error: ./usr/src/nv/nvidia.o: unresolved symbol
remove_proc_entry_Rsmp_86f7070c
./usr/src/nv/nvidia.o: unresolved symbol create_proc_entry_Rsmp_ee3233d4
./usr/src/nv/nvidia.o: unresolved symbol __pollwait_Rsmp_b99999c7
./usr/src/nv/nvidia.o: unresolved symbol change_page_attr_Rsmp_da6e8366
./usr/src/nv/nvidia.o: unresolved symbol init_mm_Rsmp_8037974a
./usr/src/nv/nvidia.o: unresolved symbol register_chrdev_Rsmp_f2287ab3
./usr/src/nv/nvidia.o: unresolved symbol proc_root_driver_Rsmp_ef7a8833
./usr/src/nv/nvidia.o: unresolved symbol mem_map_Rsmp_a799f9ba
./usr/src/nv/nvidia.o: unresolved symbol irq_stat_Rsmp_eeebfc06


Any ideas?

Looks like your kernel sources are configured for SMP, but your running kernel isn't.

Quote:

If you receive errors about unresolved symbols,
then the kernel module has most likely been built using header files
for a different kernel revision than what you are running.
-- from the README.

2.4.20 SMP HIGHMEM kernel
 
Hi,

I do run a SMP machine and the kernel headers do exactly match the kernel I am running.

Kernel rebuilt

Hello,

rebuilding the kernel with the exakt same configuration (using make config with keeping all answers, make dep, make bzImage) creates a kernel image with the same size and so I assume an exactly identical kernel. Nevertheless the unresolved symbols DISAPPEARED and so the nvidia driver now WORKS. I just have some strange artefacts I did not have with the 4191 driver. See green circled regions in attached screenshot.

Hmm... no idea on that artifacts problem, unfortunately.
