Need to recompile kernel modules


Hey guys, I upgraded etch to lenny, and along with that gcc 4.1 to 4.2.
Later, I recompiled the kernel. Now, when I reboot my kernel panics because it can't insert any modules, because they were all compiled with 4.1

How can I recompile all the modules?

Thanks for your help.

Sounds like you went behind the back of the package manager. You need to read up on apt-get. It maybe simplest just to reinstall lenny from scratch.

Doesn't make since if you upgraded to gcc4.2 and then after it was fully installed you built the kernel. Not sure but maybe the system is still 4.1 till a reboot? Would have to give this a thought to get in.

Here is exactly what I did:

1) changed all references in sources.list to etch to lenny
2) ran apt-get update
3) ran apt dist upgrade

This downloaded a lot of stuff, and installed as expected.
4) rebooted. On reboot, there was a noticable visual difference, I assumed all was well.

Then, I decided I needed to reinstall my nvidia driver, because it wasn't being detected properly (it wasn't in etch either). When running the nvidia script, the gcc version check failed, because the current compiler was 4.2, and the kernel (it said) was compiled in 4.1 .
So, I figured I would just recompile the kernel with the new gcc and all would be well. Recompile went fine, but on reboot none of the modules will insert, it is again complaining about the compiler version.

If I use a live cd will mounting the hd and running "make modules" work? Or does the make rely on a bunch of system variables that wont be set properly if I boot into a live cd?

Please help, I worked quite a bit to get the sound card to work on this machine, I don't want to run through it all again on a fresh install of lenny.

I have no ideas at the moment.

Well, I guess it is time to take the plunge, I'm going to reinstall today, I think I will go with Gutsy though. Is there a way to install Gutsy and Lenny in the same partition? Just like you can have two kernels installed on the same partition, you just boot into one or the other?
