Hi,
with latest version RX1025 I get this error_
GPU Fault detected: 147 0x0978c401
VM_CONTEXT1_PROTRECTION_FAULT_ADDR 0x04103F3F
VM_CONTEXT1_PROTRECTION_FAULT_STATUS 0x060C4001
I have a rig with 3x RX470 4GB and 1x RX480 8GB
On web page I don't have any indication of mining speed
Do you know why ?
Try without Memory OC. Helped me.
Same problem here.
One card is mining very slow as the dashboard says its clocks are 300/300. All the other cards are only running at 600~1000mhz on the core.
So I was getting 500 sol/s in Windows with claymore v4. But now only 390 sol/s with SimpleMiner 1025

EDIT: Other than the general protection fault message still appearing, I've fixed all the speed issues.
Problem with speed is random and its a kernel bug.
I am already working on new linux kernel 4.9 which generates faster rates and propobly fixes overclocking bug.
I need to test it and i think about upgrading it partially.
If you have those errors then something is wrong with this miner.
Updates v1013-2015 didnt mess with linux system itself, there were only miner updates and few other fixes.
Anyway here are variables you asked for:
Kernel 4.8.3
AMDGPU 16.30
Ubuntu server 16.04
I have working FAN speed script. propobly i will integrate today/tomorrow 
I will send email before i will make this update.
