One of my Apollo BTC's is misbehaving in a strange way.

It's few years old, Model # : FBA2001 is written on the cover. Powered by an after-market PSU, which is good, 'cause the stock PSU would have issues with what it's doing....

No matter what command I use to start it (in a terminal on a Linux SBC and also on a Linux laptop), it will always run at full bore.

That means sucks 350W (measured at the wall) and produces around 3.5 TH/s, while the terminal claims this:

BOARDS SYS INFO (1 boards, 44 chips):
BRD FOUND REV SPI PWR CHIPS ON ON_T inOhOsc OhOscN OhOscT OhN OhT loI Tc Th T, C TA RevADC OCP HE osc OSChip U, mV I, mA P, Wt

The command to start it was something like this: sudo ./start_etc..etc..etc.sh

And the text in the .sh file is this (but with proper pool and user info):
./apollo-miner -host Xxxx -port xxxx -user Xxxxxx -pswd x -comport /dev/ttyACM0 -brd_ocp 50 -osc 50 -ao_mode 1 -fan_temp_low 65 -fan_temp_hi 70 -fan_pwm_low 1 -fan_pwm_hi 100

Any idea what has gotten into it and how to exorcise whatever is bedevilling it?

Hmm looks like current control and/or one of the voltage controllers has gone bad on the main board. Unfortunately stuff like that is hard to fix without a full hashboard replacement. What mode were you running it on?
