Re: recompilar kernel com DMA
Ronaldo,
achei algo que talvez possa te ajudar
http://seclists.org/lists/linux-kernel/2002/Oct/0155.html
ele teve um problema muito semelhante ao seu. No caso dele, ele esqueceu
de habilitar o suporte no kernel, para o controlador da via. Não sei
qual é o seu caso, mas acompanhe a thread que acho que vai te ajudar.
Abraço,
Leandro Santoro.
