Here is the solution for linux amdgpu blockchain fix:
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.

Feel free to donate if you happy ;-)

Does it apply for SMOS too?

has this been confirmed ?

Just did it and getting increase. This is cool. If you follow these instructions, just append amdgpu.vm_fragment_size=9 to what's already in the grub line so it's

Code:

GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0 consoleblank=0 amdgpu.vm_fragment_size=9"

Before

After

@clintar2, may I kindly ask you for step by step instruction for linux noob user (me)? I know how to login to SMOS with root - that's easiest part but the rest of linux commands are not known for me. Should I just type each below line and press enter after each one?

Code:

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
sudo nano /etc/default/grub
GRUB_CMDLINE_LINUX="amdgpu.vm_fragment_size=9"
sudo update-grub
sudo reboot

What does it mean:

Code:

choose new Kernel and its done!

How to do that? When/where?
