Hi all, I think the problem is that modprobe looks for the module (which in this case is aliased as "off") in /sys and raises an error if it doesn't find it (there's no such thing as an "off" module in /sys).
In the attached patch I check that the module name is not "off" or "null" before doing assert(kmod_module_get_initstate(m) == KMOD_MODULE_BUILTIN). This solves the problem on my systems. Please review my patch and let me know if there's anything you'd like me to change. Thanks, -- Alberto Milone Software Engineer Hardware Enablement Team Professional and Engineering Services
