Guix deploy fails claiming some module missing

[Wicki Gabriel (wicg)]

Hi

I've been developing for/on a Raspi and successfully built images and deployed 
to the machine, but at some point in time deployment failed with this message:

missing modules for #<file-system-label "Guix_image">: uio_pdrv_genirq

I am not sure what had changed in my code base that would lead to this error, 
and I am somewhat puzzled over the fact that building the system (image) itself 
works but deploy fails?
Also, the module is loaded in the running system.

Any ideas/hints/pointers?
