GPU lockup on AMD A4-3400 APU when starting X server on opensource drivers. (works fine with fglrx)

Description

I've had this lockup on this machine for the past few years, across several different kernel versions, different distributions, etc. Booting with KMS works fine, but the second a graphical environment starts (whether X or wayland-based), it locks up.

Booting Ubuntu with user-space mode-setting works, and then I can install FGLRX from there and everything works fine. After speaking with airlied on IRC, they suggested it could be a workaround that AMD has put into FGLRX that never made it into the opensource drivers, and that AMD might have to look into it.

CPU/GPU : A4-3400
Motherboard : GA-A75M-D2H ( http://www.gigabyte.com/products/product-page.aspx?pid=3930#ov )
