KERNEL LOG: https://ghostbin.com/paste/7t8fh

My # CHAIN1 card does not work, so the log should show it faulty.

Today BitMain support me answered this here:

"Dear Marcos,

Thanks for your consultation!

Please try to replace with a good known control board. Kindly let me know if it works.

This is a control board.

And now, what should I do, Blissz?
