Invalid Hardware/Firmware Combination

What does 1 (Argument: 8) mean?

An invalid combination of controller hardware and firmware has been detected. This means the installed firmware version is incompatible with the controller's hardware revision, preventing proper operation and potentially causing system instability.

• Firmware updated to an unsupported version for the specific hardware revision of the controller.
• Incorrect controller hardware revision for the installed firmware.
• Corruption of firmware leading to misidentification of hardware compatibility.
