I tried but I haven't seen the WARNING anymore...it smell like a race condi= tion (at least this is what is usually "fixed" by printings :-D). I also retried to insert the module without the debug option but I didn't g= et the error anyway. This means that I get the error only at boot. I will try to make more tests and eventually report what I see/understand. Thank you for the work done so far! Cheers, --=20 Antonio Quartulli =2E.each of us alone is worth nothing..
