That's the tip I was hoping for! I've missed CONFIG_SCSI_LOWLEVEL because I was looking for answers here: https://cateee.net/lkddb/web-lkddb/SCSI_ISCI.html. It's the first time that that database gives me wrong information... Conversely, this website is correct: https://www.kernelconfig.io/config_scsi_isci?q=3D&kernelversion=3D5.4.230&a= rch=3Dx86. 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!
