Hi,

I have an Xtreamer mxV Pro S905 TV box which is a clone of the popular 
KI PLUS boxes.
I am using the mainline DTS for the Amlogic P201 development board which 
has similar hardware.

I have been trying mainline Linux since 4.10 and I have always had 
random oopses during boot.
Up till now I put this down to "early days" but as they continue with 
4.13.0-rc2 I thought I should report them.

Here are some extracts from boot logs concerning configuration, errors 
and warnings:-

I added irqpoll to the command line as suggested in the boot log above 
and I got these significant differences:-

I should be grateful for any information on whether these are real 
problems or if I am doing something wrong.
If my log extracts are insufficient I should be pleased to supply any 
missing information.

I am then running Ubuntu 17.04 without an initramfs.
It works fine headless and is stable even after these oopses.
However unfortunately I have never been able to get Mali to work on 
mainline despite trying several recipes.
If anybody can point me to one that works with 4.13.0-rc2 I should be 
most grateful.

I now boot from a USB stick as I have fried two UHS-I micro-SD cards 
during my experiments.
I suspect that they may have been over-voltaged by my box.
Has anybody else had this problem?

TIA.

Cheers,
Chris
