CONFIG_SCSI_ISCI depends on CONFIG_SCSI_LOWLEVEL.  Is it set?

That's the only possibility I see, apart from the obvious 
CONFIG_SCSI.

Otherwise, share your (Guix-generated, final) .config.

I'm confused by your explicit reference to 
gnu/build/linux-modules[.scm], which provides a set of mechanisms 
to work with modules.  It *should* not set policies or ‘require’ 
any ones in particular.  Does it?

Do you mean ‘%base-initrd-modules’ in 
<https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/system/linux-initrd.scm#n342>?

This static list can be frustrating, but we can easily remove 
elements from it or even replace it entirely:

 (operating-system
   …
   (initrd-modules
     ((@ (rnrs lists) remove) "isci" %base-initrd-modules))
   …)

What I suggest you do instead (because it's what I do to my 
kernels :-) is simply ship a ‘%xenomai-initrd-modules’ variable 
along with your ‘xenomai-linux’ package, keep them in perfect 
harmony yourself, and ask users to use both.

Kind regards,
