Anyone with a amd/radeon GPU rig running on linux?

You'll likely run into PCIe atomics issues using ROCm with Radeon cards of prior generations than Vega if they don't get full PCIe 3.0.

GFX8 GPUs
"Polaris 11" chips, such as on the AMD Radeon RX 570 and Radeon Pro WX 4100
"Polaris 12" chips, such as on the AMD Radeon RX 550 and Radeon RX 540

As described in the next section, GFX8 GPUs require PCI Express 3.0 (PCIe 3.0) with support for PCIe atomics. This requires both CPU and motherboard support. GFX9 GPUs require PCIe 3.0 with support for PCIe atomics by default, but they can operate in most cases without this capability.
