You yourself have stated that your boards are failing to hash.

It looks like some form of system test against the boards is failing.

I know I am being captain obvious here.
chain[6]: some chip cores are not opened **FAILED!**
**Test Patten** on chain[6]: **FAILED!**

Until you can find the point of failure with a volt meter, or replace the failing boards.

You can try tuning the voltage / frequency of the miner to see if this helps stabilize them.
