The above is wrong. |

The kernel (and modules) record what version of GCC they were compiled |
| 40 |
with. This version is checked at module load. If the kernel's GCC |
| 41 |
version doesn't match the modules GCC version, the module loading fails. |
| 42 |
This only becomes an issue with modules that are compiled outside of |
| 43 |
the kernel tree [1]. |
| 44 |
|
| 45 |
To fix this you have two options. either switch out which version of |
| 46 |
gcc you are using and recompile modules that are maintained outside of |
| 47 |
the tree, or recompile your kernel with the current version of gcc. |
| 48 |
|
| 49 |
First though, you need info: |
| 50 |
|
| 51 |
# modinfo <modname> | grep vermagic |
| 52 |
|
| 53 |
# cat /proc/version |
| 54 |
|
| 55 |
# gcc-config -l |
| 56 |
|
| 57 |
I would recommend recompiling the kernel, but it's up to you. |

[1] - The caveat being when the GCC version has changed after the kernel |
| 64 |
tree was already compiled and installed, and you are recompiling the |
| 65 |
kernel tree for one module, without cleaning the tree. |
