The code that's executed seems to be: dvd_authinfo auth_info; memset( &auth_info, 0, sizeof( auth_info ) ); auth_info.type = DVD_LU_SEND_AGID; auth_info.lsa.agid = *pi_agid; i_ret = ioctl( i_fd, DVD_AUTH, &auth_info ); anybody here have any idea what might cause this? could this really be just a caching problem caused by the new vm or is this something completely different I observe here? The -ac kernel series doesn't seem to have this problem on the same machine.
