        Kernel driver in use: cciss

Ecco che cosa mi è venuto fuori!
Dove trovo il vendor ?

Ne approfitto per chiedere un'altra cosa. Attualmente tale controller è
gestito con i kernel driver cciss. Ammesso che riesca trovare il modo di
dare il comando che mi avete suggerito,  il sistema si "arrabbia" se
carico un nuovo driver per un device che è già gestito con un altro?

Grazie...

Ciao
