I have a PC running gentoo with a 2.6.11-gentoo-r6 kernel. It all appears to work as it should and I am now trying to get a DVB card running on it.

I have downloaded a video4linux patch that I understand is necessary for this and have applied it to my kernel sources. The patch appears to go OK - no error messages of any kind.

I then do a make menuconfig and set the options required for my DVB card.

I then make and make install, all of which appears to go OK. Point grub to my new kernel and reboot. I now get the following error messages on all my modules

FATAL: Error inserting <path>cx88xx.ko: Invalid module format

My new kernel is called 2.6.11-gentoo-r6-kraxel1

If I do dmesg I see a message saying -

cx88xx: version magic '2.6.11-gentoo-r6' should be '2.6.11-gentoo-r6-kraxel1'

Now I interpret this as meaning that the new kernel is trying to load modules for the old kernel and not the ones I compiled for the new one - and it doesn't like it.

Can anyone tell me if my interpretation is right and where I go to fix the fact that the modules are being pulled from the wrong directory?

Thanks

I didn't see "make modules_install" in that list. . .

Ummm...I did do that...I 'm sure I did that.....didn't I? OK.. I'll try it again before I put on my "meet Mr Stupid" hat.

Cheers

No, I did do that, sorry should have said. I do make modules and then make modules_install. I get the same thing. Invalid format. Any idea's?

Cheers

In your config, set General setup -> Local version to kraxel1 and redo the make && make modules_install.

OK, good call syg00, I now can use the driver modules I need. Unfortunately X now fails to start reporting an error in /var/log/Xorg.0.log -

(EE) NVIDIA(0): Failed to Initialize the NVIDIA kernel module.
(EE) NVIDIA(0): *** Aborting ***
(II) UnloadModule: "nvidia"
(EE) Screens found, but none have a usable configuration.

This works fine with my normal kernel, why should the patched kernel have killed it?

Every time I fix one thing I seem to break something else, its very frustrating :-(

Cheers

You need to reinstall Nvidia when you use a new version of the kernel - it's not a bad idea to get into a routine of re-emerging Nvidia every time you compile a new kernel. . . so see if that fixes it!

Thats fixed that bit, thanks! I'm another tiny baby step forward

I had a similar problem whereby

# uname -r

Would report a different version number than the local version configured when compiling the kernel.

I'm retrying it now, after i've emerged "git" - the comment in the config says something about it requiring "git" to work.
