Yes yes yes!
That's the tip I was hoping for! I've missed CONFIG_SCSI_LOWLEVEL
because I was looking for answers here:
It's the first time that that database gives me wrong information...
Conversely, this website is correct:

And for the module list, I was blaming linux-module.scm because the
system reconfigure was failing at that point. Looking in the code I
knew that the list was generated elsewhere, but I couldn't find where,
nor how it is passed to linux-modules... I admit I've just wet my toe
in Guix (and guile programming) and the codebase is huge...

Thank you very much. Now my system reconfigure ended correctly! Time
for latency tests... :-D
