Yeah this is a known bug in hwsim - if registration fails (here apparently because you have no rate scaling) then it crashes - the error path is broken. Luckily, this never actually happens in practice. I'm supposed to get some patches from Marcel which I think will (have to) fix this. johannes -- Intel GmbH Dornacher Strasse 1 85622 Feldkirchen/Muenchen, Deutschland Sitz der Gesellschaft: Feldkirchen bei Muenchen Geschaeftsfuehrer: Christian Lamprechter, Hannes Schwaderer, Douglas Lusk Registergericht: Muenchen HRB 47456 Ust.-IdNr./VAT Registration No.: DE129385895 Citibank Frankfurt a.M.
