Hello @Achilleas-Kotsis,
why do you use the dkms and not the pre-compiled modules? What is your setup?

Achilleas Kotsis

@cleve Because I never use precompiled modules on debian based systems if I can help it since dkms was introduced in the '00s, I like the flexibility of not having to match kernels with specific precompiled modules.
For example, right now on one of my systems:
unipi-kernel-modules : Depends: linux-image-rpi-v8 (= 1:6.12.20-1+rpt1~bpo12+1) but 1:6.6.74-1+rpt1 is to be installed

I have multiple rpi3 and rpi4 based neuron systems that I maintain, most are runing raspberry pi os bookworm aarch64. BTW unipi-kernel-modules-dkms=2.70~bookworm builds just fine until at least linux-image-6.6.74+rpt-rpi-v8
