Iwlwifi Firmware Failed To Load Iwl-debug-yoyo.bin «2026 Release»

The kernel reports specific return codes:

If your WiFi works but you want to clean up your logs, you can disable the "INI" (Internal Next Information) feature that triggers this debug load attempt. iwlwifi firmware failed to load iwl-debug-yoyo.bin

Because the driver attempts to load the debug file, fails, logs it, and then successfully loads the operational firmware. The error is purely informational. The kernel reports specific return codes: If your

iwlwifi: Probe request failed: -ENOENT iwlwifi: Unknown firmware format Direct firmware load for iwlwifi-ty-a0-gf-a0-72.ucode failed with error -2 but the file is empty

sudo apt install git git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git sudo cp -r linux-firmware/* /lib/firmware/ sudo update-initramfs -u

The error will disappear because the driver finds a file, but the file is empty, so the debug subsystem may fail silently. You won't get debugging, and your actual Wi-Fi remains broken if the real firmware is missing.
