That's possible, after several Arch Linux upgrades, the same kernel
build for Arch Linux doesn't provide proper real-time abilities
anymore, but it's still possible to boot it.

I wonder why it was possible to build the kernel for 16.04 without
getting an error message.

FWIW this is the script that "successfully" build the kernel packages:

http://pastebin.com/LCNcsWyz

Pastebin takes a while, because the script starts with the config.
The comment on top of the script is a reminder, mentioning that it's
the same kernel I build 2015, running without issues on 15.10. Once
pastebin is ready, scroll to the end of the script, to skip the config.

BIOS

Ubuntu 16.04, GRUB2

A lot, but I'm just using a few, so I don't know which actually still
work. But Ubuntu 16.04, formerly 15.10, Arch, FreeBSD and a very old
Suse install are used and should work. FreeBSD is broken, after GRUB
was installed by the release upgrade from 16.04 to 15.10. before the
upgrade no GRUB package was installed for the Ubuntu install.

Actually I write grub.cfg manually, just for testing purpose I run
grub-mkconfig for the Ubuntu install.
