Hi, I've patched the Linux Kernel v5.15.7 with rt23 and used menuconfig to select the fully preemptable kernel. The boot process for two modules reports an unexpected version magic. It reads the following: <module name>: version magic '<kernel version> SMP preempt mode_unload <arch>' should be '<kernel version> SMP preemp_rt mod_unload <arch> This only happens for two modules, and I've built all the modules under the same source tree with the same make command. This warning makes sense since I have indeed built and imaged my SOM with the preempt kernel. The command 'uname -v' returns, "SMP PREEMPT_RT <date>". Even though I've never built this source tree without the PREEMPT_RT patch, I've done a clean build to remove any doubt about obsolete object files. Can offer a hint as to what I need to change to get those modules to build with the correct version magic? Thank you for any help, Brian
