If your Wi-Fi is and you see this message alongside other errors (like "Failed to start RT ucode"), the "yoyo" error is likely a distraction. The real issue is usually a missing or incompatible primary firmware file (e.g., iwlwifi-QuZ-a0-hr-b0-59.ucode ). In this case, ensure you have the latest non-free firmware packages installed from your distribution's repositories.
Here is a helpful guide on why this happens and how to fix it.
