Hi, more news. This morning the bluetooth (ever with kernel 4.17.15-1) is missing again. So I had remembered that when I run an update that calls initramfs, the bluetooth at the new boot doesn't work, so first I have to do a reboot to run update-initramfs -uk all && update-grub2 && grub-install then reboot again and the bluetooth works. So I have done the above procedure and the bluetooth has worked again. But I had a dubt: may the problem with the last kernel be the same? Again: - updated the kernel to 4.17.17-1; - rebooted; - update-initramfs -uk all && update-grub2 && grub-install; - rebooted; - bluetooth works with kernel 4.17.17-1 too. I had reported a similar bugs (Bug#814508: initramfs-tools: bluetooth/hci fails) time ago and I think are related, the real problem is initramfs. Thanks -- Stefano Callegari
