RHEL8 based system has multiple kernels but module will only load in one of them

As the title says I have multiple kernels on my system

4.18.0-193.19.1.el8_2.x86_64
4.18.0-240.el8.x86_64
4.18.0-372.26.1.el8_6.x86_64

Issue is I am using mpt3sas on my system and when i installed it on 4.18.0-193.19.1 it was perfect. Now on a later kernel I am seeing that kernel does't detect that module. I can't modinfo it or modprobe it. But when I attempt to install it it does detect that it's already installed. It is in the /lib/modules/4.18.0-193.19.1.el8_2.x86_64/weak-updates & /lib/modules/4.18.0-193.19.1.el8_2.x86_64/extra directories if that makes a difference.

Any ideas on what I can do? Should I uninstall it and reinstall it on the newer kernel? I attempted to copy the directories & .ko files but that didn't make a different it seems.

EDIT: I attempted to remove the old version in there and install it via dnf and now it seems I have two version installed on the system. Here is the output of modinfo mpt3sas:

Kernel modules are specific to kernel versions and a new kernel requires that the module gets updated/recompiled as well.

When the original provider hasn't built the required new binary RPM package yet, install the source package and build your own binary RPM package that matches your new kernel i.e.

See for example https://www.ibm.com/docs/pt/ess-p8/5.1.0?topic=guide-instructions-updating-mpt3sas-driver

Download the SRPM

Rebuild the RPMs for the running kernel.

rpmbuild --rebuild SRC_RPM_LOCATION/mpt3sas-13.100.00.00-1.el7_2.src.rpm

This command creates two RPMs.

Unload the current mpt3sas driver.

rmmod mpt3sas

Install the RPMs.

rpm -Uvh /root/rpmbuild/RPMS/ppc64le/kmod-mpt3sas*rpm
rpm -Uvh /root/rpmbuild/RPMS/ppc64le/mpt3sas*rpm

Load the updated modules.

modprobe mpt3sas

Verify that the module is loaded.

modinfo mpt3sas

Attempted to rebuild with this command but I only have the kmod driver, not the mpt3sas driver `rpmbuild --rebuild kmod-mpt3sas-28.100.00.00-3.el8_2.elrepo.x86_64.rpm` `Installing kmod-mpt3sas-28.100.00.00-3.el8_2.elrepo.x86_64.rpm` `warning: kmod-mpt3sas-28.100.00.00-3.el8_2.elrepo.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID baadae52: NOKEY` `error: source package expected, binary found` `error: kmod-mpt3sas-28.100.00.00-3.el8_2.elrepo.x86_64.rpm cannot be installed`

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
