S 7 Hasing board problem (Stange problem)

[vladimir84]

I have starnge problem with hashing board.
When antminer starts with that board red light on board is active,temperature rising to 52C and all chips (45) are active (ooooo ooooo ...)
On hashing speed and awerage speed are shown 0 (no hashing) and only shows local work (rising)
Temp is 51-52 (board is hot)
Chips are active
But no hashing!
What can be problem? (power supply is ok because work on other board fine)

The S7 boards will heat up if they are powered whether they are mining or not. I would say post the kernel log and we can tell you better whats happening. Also I would post this under the Mining Support section
