sorry had to change username.
I have the Bitmain PSU, I have swapped the cables on the PSD and the others just to check. The fans is running and everything seems to work except it doesnt hash. I have also reloaded the latest firmware and rebooted. The kernel log shows some errors and the last is "FPGA don't code"
I am not familiar at all with Linux. Below is the log:
