Well, I will attach the dkms log file, but I don’t know what more details 
I could give.
I’m compiling my own kernels from kernel.org. I don’t have problems with 
6.17.x, but with 6.18.2.

The error above mentions an unexpected operator. I’m using Testing, 
/bin/sh is a link to dash. So maybe there is an error when the versions 
are compared and the experimental flag is not properly set.

I have seen a new ZFS version in experimental. So maybe I should test the 
new one.

Many greetings,

	Stephan
