Probelms after make modules_install

Hello. I changed my alsa drivers from being in the kernel to being a module using make menuconfig and then perfomed make && make modules_install.

As it turns out I need to use my old kernel because of other constraints, but now my modules are all f'ed up. I am still using the original bzImage of the kernel so nothing has changed there, but the modules do not load at boot. It can't load vfat for starters and I have no network.

The output of /var/log/kernel/current tells me stuff like:

You can't just revert back to the old kernel - the modules are always built specifically for the one you make at that time.
If it were an older version there would not be a problem, since their modules would not be overwritten, but here they are - and they don't match.
Hence, breakage.
Copy back your original config and rebuild again.

well i did do undo the changes I made for make menuconfig and redid make modules_install, but not make && make modules_install.

The problem is that the new kernel that gets compiled won't even boot the machine, there is obviously something different with how it was built vs what make does on my machine.

There are other machines around that I could use to copy the old kernel and modules from. Would something like that work. They were all built from the same install cd with the same configuration.

Dangerous regardless, unless you have implemented very strict build requirements for every one.
What you should do is copy over the config and rebuild.

Unless it is actually a problem with the toolchain - but the build wouldn't even complete successfully in that case.

Nonsense; like I have said twice now, copy a working .config file over and rebuild the kernel.
Takes less than 20 minutes.

You are mixing kernel and modules in a crazy manner. Make sure /boot is mounted and then do it the correct way:

Moved from Installing Gentoo to Kernel & Hardware.
Not in installation problem.
