I just bought a Gigabyte "GV-R737WF2OC-2GD" (R7 370). Same problem: unable to boot Linux (Fedora 23 GNOME Workstation) Same fix: radeon.dpm=0
It was provided with a VBIOS "015.048.000.061" (F2 release) which I updated to "015.048.000.069" (F3 release) without improvement. http://www.gigabyte.fr/products/product-page.aspx?pid=5469#bios
The card works on Windows 10.
You gotta read your VBios and insert values into the kernel source's drivers/gpu/drm/radeon/si_dpm.c into the quirk list. Google it for how to do that. Basically, you'll have to get such software (techpowerup provides one, as far as I remember) and then for your working system, put the needed ones in thay file and recompile your kernel. Then you may even send a commit :)
