The new ROCm Kernel works great, my hashrate went from 155 > 167Mhs/s with 6*RX470 with Ubuntu 16.4
#Install new ROCm Kernel:
wget -qO - http://repo.radeon.com/rocm/apt/debian/rocm.gpg.key | sudo apt-key add -
sudo sh -c 'echo deb [arch=amd64] http://repo.radeon.com/rocm/apt/debian/ xenial main > /etc/apt/sources.list.d/rocm.list'
sudo apt-get update
sudo apt-get install rocm
#edit grub
sudo nano /etc/default/grub
#2MB fragments for Ellesmere are enabled with a grub option:
GRUB_CMDLINE_LINUX="amdgpu.vm_fragment_size=9"
sudo update-grub
sudo reboot
choose new Kernel and its done!
Thx to gstoner from ROCm Github.

This does not work for me, after changing the kernel my hashrate is dancing between 25 and 29

you need to fix your clk level. i do this with roc-smi
look here https://github.com/RadeonOpenCompute/ROC-smi
I was using rocm-smi before installing this kernel with a custom bios to underclock-undervolt my card, I used this command in my script before launching Claymore with no changes in the hasrate dancing
My clock is at level 3 when Claymore is running
==================== ROCm System Management Interface ====================

GPU[0] : GPU Clock Level: 3 (1145Mhz)

How do you fix your clk level?, what command do you launch?...
Regard
I use this:
echo yes | /opt/rocm/bin/rocm-smi/rocm-smi --setsclk 4
Same result... sometimes 29, sometimes 24, sometimes 27 :´(
