Just got this from Gigabyte Support: "Hello, Sorry but Gigabyte do not guarantee Linux Platform on the desktop motherboard. It support for Windows 10/7."
Extremely helpful :/ In the meantime, I booted the Kubuntu install ISO with acpi=off setting. The same option was required for the first boot after install. Kernel version 4.10.0-21 compiled by kaihengfeng on http://people.canonical.com/~khfeng/lp1671360-2/ seems to work fine, the only thing to report is a long boot time.
