After upgrading from 4.5.7.201606222150 to 4.5.7.201606302132 my server refused to boot (hangs on motherboard splash).
Chrooting from a live USB stick and downgrading to 4.5.7.201606222150 fixed it.
I can't find any logs of the boot attempts but maybe I just don't know where to look.
After booting successfully, "journalctl -b -1" showed the boot where I did the upgrade.
My distribution is an up to date Arch Linux.
My motherboard is a MSI 970A-G46 (MS-7693), BIOS V2.6.
My boot loader is systemd-boot (UEFI).
I hope those information will be useful to someone.
