There is the same problem with manjaro (linux kernel 5.8)

[kdehairy]

I have the same issue on archlinux kernel version 5.8.13).

It seems that mmap_sem is renamed to mmap_lock on kernel 5.8

[Weirdo1312]

same issue here on arch linux with 5.8 kernel
logs:
make.log
make(1).log

[kdehairy]

I ended up compiling the kernel with the modules built in to overcome this. Now it works!

Had the same problem in kubuntu

I managed to compile the Tumbleweed package using @choff fork however it is for Tumbleweed only. I will submit my changes once I figure at least 15.3 compatibility and sign the modules for secure boot
