as we've got a working 4.9 grsec release now I wanted to try out the experimental amdgpu support for my radeon SI card.
Unfortunately there seems to be a size overflow somewhere which doesn't let me boot grsec with amdgpu.
GPU: Radeon HD7850 Eyfinity6
Kernel: 4.9.9
Grsec: 201702122044
I'm happy to test any patches
