It means that the module must be compiled against the sources for the
kernel that is running when the module attempts loading. The lkpi is NOT
stable. If it has changed between the kernel that the drm-kmod was built
against and one running, a fail is likely and it is usually a panic. That
is definitely the case between 12.1 and 12.2 as well as between
12.2-RELEASE and 12.2-STABLE. If you have multiple systems running the same
version of the kernel, you need only build the port once and "make package"
after the build but before cleaning and adding the generated package file
on other systems.
