Hello all,

I have an issue I hope someone could help with.

I have 4 T9+ miners and they have all been working pretty great this past month but a few days ago one of them dropped to 8TH/s
I went to check and I saw that one of the boards seems to be running really slow. Chain 2,9,10


Here are steps I have tried:
Restart
Reset to factory via button
Reset to factory via software (web gui)
Reset to factory with IP Report button
Upgrade firmware to latest from BITMAIN site
Switch powersupply from another miner

I am begging to think it is a hardware problem but ASIC status doesn't show anything wrong.

Here is my Kernel Log https://pastebin.com/J20UYVky

I hope it is not hardware and someone could help me, but if it is I would like to at least know for sure that it is hardware issue.
Please advise

Thank you in advance
