--- Comment #4 from James Le Cuirot (chewi@gentoo.org) --- Not sure if this is related to bug #199653, which concerns freezing on the 2500U and 2700U. It hasn't received any attention from AMD or other kernels devs but there is more information that could potentially be useful. I tried amdgpu.vm_update_mode=3 but that didn't help.
