Modules do not load

In case a specific module does not load and the boot log (accessible by running journalctl -b as root) says that the module is blacklisted, but the directory /etc/modprobe.d/ does not show a corresponding entry, check another modprobe source directory at /usr/lib/modprobe.d/ for blacklisting entries.

A module will not be loaded if the "vermagic" string contained within the kernel module does not match the value of the currently running kernel. If it is known that the module is compatible with the current running kernel the "vermagic" check can be ignored with modprobe --force-vermagic.
Warning: Ignoring the version checks for a kernel module can cause a kernel to crash or a system to exhibit undefined behavior due to incompatibility. Use --force-vermagic only with the utmost caution.
