On my previous comment "does not appear in kernel grub" was corrected by making "sudo update-grub2" in the main partition, with Ubuntu 14.04.3 (I use 3 partitions with 3 different OS,). In previous tests I did run "sudo update-grub2" in ubuntu 15.10 just after installing the kernel.
Thanks. Now, it is already fixed this bug.
