Kernel Module Operator was being used to load drivers for QDU x100 DU PCIe card on OCP v4.12 without issues. Post upgrading to v4.14+ the mhi module is now being included in kernel 5.14 --> https://elixir.bootlin.com/linux/v5.14.21/source/drivers/bus/mhi/core
obj-$(CONFIG_MHI_BUS) += mhi.o)

So, now when loading this module, it causes issues

OCP v4.14+

Any OCP version utilising kernel v5.14+ might hit this issue

Using the below resource on cluster v4.14+ causing issues

Kernel module gets loaded & is usable

They still will need to load their OOT module as the upstream version doesn't have required drivers for QDU x100 DU PCIe card. I suggested them to follow documentation --> 4.7. Replacing in-tree modules with out-of-tree modules(https://docs.redhat.com/en/documentation/openshift_container_platform/4.18/html/specialized_hardware_and_driver_enablement/kernel-module-management-operator#kmm-replacing-in-tree-modules-with-out-of-tree-modules_kernel-module-management-operator)

The issue still happens
