--- Comment #2 from XoD xoddark@gmail.com --- It seems I don't have the latest rlc firmware, I have updated them and I currently rebuild the kernel 3.10.7 for test again.
But I'm not sure than the firmeware are include in the initrd/kernel, how I can verify this ? (I use a kernel configuration derivated from the configuration of the ubuntu kernel).
