I have used Sil SATA controller, Matrox g550, few NVidia cards and two
Radeon ones (HD5450 and R240) with APM Mustang (also X-Gene1 like
Gigabyte). All with 64KB kernels.
Radeon sits in this machine since my "AArch64 desktop week" which was
September 2015. Used that card since 3.19 kernel and went through all
versions used in Fedora/rawhide.
I rather suspect Gigabyte firmware having some issues. Try booting with
"acpi=off" and proper DTB to make sure that it is not ACPI related?
