When trying to start X, I get the following message:

(EE) NVIDIA(0): Failed to initialize the NVIDIA kernel module!
(EE) NIVIDIA(0): *** aborting ***

After google and poking around in some log files, I have found that when I run

insmod nvidia

I get the following output (hand typed):

Using /lib/modules/2.4.21-0.13mdk/kernel/drivers/video/nvidia.o
Warning: loading /lib/modules/2.4.21-0.13mdk/kernel/drivers/video/nvidia.o will taint the kernel: Non-GPL license
See [....] for information about tainted modules.
/lib/modules/2.4.21-0.13mdk/kernel/drivers/video/nvidia.o: init_module: Device or Resource busy.

This is a new problem, everything was working fine last week. I did some searching, and although I can't find the exact same problem, similar problems with different cards imply changing the IRQ/PORT settings.

Does this seem reasonable? How do I view/edit the current hardware configurations?

This is running Mandrake 9.1, 2.4.21-0, with GeForce drivers installed by using the "nvidia-install --update" command.

Thanks,

some files like /proc/iomem /proc/ioports /proc/interrupts allow you to view different point of your hardware config. Also another important directory for you is /proc/driver/nvidia.
Another interesting command is lspci (and setpci) which allow you to view/set your PCI config.
Hope this will help you

Yeah, I didn't understand much of what was going on in those files. However, there turned out to be a quick way of fixing the problem:

(On Mandrake):
telinit 3
nvidia-installer --uninstall
# Then re-install the basic driver download from NVIDIA.
nvidia-installer --update
telinit 6

At some point, this waxed my console, which is why I had to reboot instead of just starting X.

Thanks,

I take that back, don't run nvidia-install --update. When it reboots, it has the same problem.

Any ideas where I could file this as a bug-report?
