lots of unresolved symbols when loading nvidia.o kernel module
Ok, im trying to install NVIDIA kernel module, tried like 4 different versions, and I always
get these unresolved symbols error, ill paste part of them. I'm running Slackware linux 9.0 with 2.4.20 kernel. and I have ASUS nvidia geforce MX440 AGP8x 64 Mb video card, any ideas ?
It seems that the module compiles perfectly, but the error occurs when im trying to load the module.
error as follows: (it's just part of it, there are more unresolved symbols...)

/lib/modules/2.4.20/kernel/drivers/video/nvidia.o: unresolved symbol pci_read_config_word_Rsmp_923654cb
/lib/modules/2.4.20/kernel/drivers/video/nvidia.o: unresolved symbol request_irq_Rsmp_0c60f2e0
/lib/modules/2.4.20/kernel/drivers/video/nvidia.o: unresolved symbol bh_task_vec_Rsmp_284177b8
/lib/modules/2.4.20/kernel/drivers/video/nvidia.o: unresolved symbol do_gettimeofday_Rsmp_72270e35
/lib/modules/2.4.20/kernel/drivers/video/nvidia.o: unresolved symbol __tasklet_hi_schedule_Rsmp_60ea5fe7
/lib/modules/2.4.20/kernel/drivers/video/nvidia.o: unresolved symbol __pollwait_Rsmp_90dd51e4
Hint: You are trying to load a module without a GPL compatible license
and it has unresolved symbols. Contact the module supplier for
assistance, only they can help you.

/lib/modules/2.4.20/kernel/drivers/video/nvidia.o: insmod /lib/modules/2.4.20/kernel/drivers/video/nvidia.o failed
/lib/modules/2.4.20/kernel/drivers/video/nvidia.o: insmod nvidia failed

Do you have more than one kernel-source on the system? Is it possible the compiler got ahold of the wrong kernel headers when building the module? The kernel source tree needs to be at least mrproper too, but not necessarily compiled.

Indeed. My second guess would be that an inconsistent kernel source combined with CONFIG_MODVERSIONS=y is also responsible for breaking the nvidia module.

Had the same problem, it turned out that the issue was with my kernel config file (/usr/src/linux-2.4/.config or /usr/src/linux-2.4/configs/kernelrel-basearch.config), there were some settings in there that messed with the nvidia kernel build.

You could go through each setting and then do a new make kernel and module build but I found the easiest (and quickest way) was to download and reinstall a clean kernel-source.
