Antminer S19 – Hashboard Initialization Failure
chain init failed
Critical — Immediate action required
Symptoms
- Hashboard starts but fails during initialization
- Kernel log shows init failure with error codes
- Hashboard may work intermittently
Step-by-Step Fix
Power cycle the miner completely (unplug, wait 30 seconds, replug).
Reseat the hashboard ribbon cable.
Check for firmware corruption — try reflashing the firmware.
If init fails consistently, there may be a communication issue between the control board and hashboard.
Professional diagnosis needed if ribbon cable and firmware are confirmed good.
