For those mining using:

• Linux Ubuntu Server 16.04
• GPU RX580

If you are using proprietary AMD's driver amdgpu-pro driver you might have noticed the hash rate is not stable and dropped. This is due to that Security Issue found on Intel chips recently.

I know the solution is to disable automatic updates of the kernel and to "roll back" to previously "good working" (for mining) Linux Kernel Version.

What I would like to know is what version of the Linux Kernel (4.4.xx or 4.10.xx or 4.13.xx) you found to be more stable and optimized for mining?
Is it the normal version or the HWE version?

P.S.: if your rig is still stable you can get this info by typing: uname -a
