I have hybrid graphics on Lenovo Ideapad 720 laptop (Intel i7 8550U and AMD RX 560), use amdgpu and i have randomly hangs with kernels > 5.0.13.
AMDGPU hangs on laptop returned from hibernate, but on latest time i go to 5.2.8 and now AMDGPU hangs on normal work (only suspend to ram, without hibenates).

Can you bisect?
I started bisect, but found that I was using an outdated version of the OpenCL libs from amdgpu-pro :(
After updating libs randomly hangs was stopped.
Another problem with return from hibernate i will testining and will open new ticket if bug exists.
Please close this bug, i'm sorry for my carelessness.
