 Posted: Sun Jan 29, 2006 10:33 pm Post subject: Kernel modules won't load after rebuilding kernel [SOLVED] |
 |
|
I just rebuilt my kernel (make && make modules_install && make install) and after a reboot, none of my modules in autoload.d (bttv, snd-via82xx, nls_utf8) accepts to load - they are complaining about "invalid module format". I have done nothing odd since the last time time I modified my kernel (not even an update world). Make clean doesn't help.
When I try make modules, it doesn't seem to actually rebuild any module.
This is with gentoo-sources-2.6.15-r1.

Check errors in dmesg. Are you sure you mounted /boot before running make install?

Just typing make will make both the new kernel and the new modules, make modules_install is then enough to install the modules in their proper locations. Have a look in /lib/modules/gentoo-sources-2.6.15-r1 if the modules are actually put there. Did you rebuild the same kernel, or have you changed to a new version?
I only ever use this command:
| Code: | | make && make modules_install |

The modules are not put in /boot, if he forgot.. then the old kernel would have been loaded and he would not get any errors. At least, that's what I think.  |

make install does not install modules, but the kernel in the /boot partition.
To install the modules you do make modules_install which you did.
Try again to recompile your kernel and see if will accept the modules you are loading. Also make sure that you have selected the needed modules as M in the kernel, not *. |

If he forgot he's running the old kernel with the new modules. Depending on configuration changes (changed compiler, changed PREEMPT, changed SMP) modules will refuse to load. That's why dmesg should be checked for specific errors.

| I had indeed forgotten to mount /boot (mainly because I was used to having /boot on the same partition as /). Thanks folks. |
