Panic report

Hola!

hace unos días cambié la RAM a mi iMac de 2011 y también le instalé un Bluetooth externo 4.0. Ahora me aparece un mensaje de kernel cada vez que lo enciendo y se apaga. Ya no sé si se debe a la RAM o al Bluetooth. Copio y pego parte del informe de error aquí abajo. Muchísimas gracias por vuestra ayuda!
