[EDITED] firmware: failed to load iwl-debug-yoyo.bin (-2)

[ticojohn]

I don't know if others are seeing the message, but on my Intel NUC, running Bullseye amd64, I have been seeing these messages at startup for quite some time.

Code: Select all

firmware: failed to load iwl-debug-yoyo.bin (-2)
firmware_class: See https://wiki.debian.org/Firmware for information about missing firmware
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=966218

And it really bugged the heck out of me. So I did some research and found that this message is apparently a false message as that binary doesn't exist. Go figure. Anyway, in the Debian bug report
https://bugs.debian.org/cgi-bin/bugrepo ... bug=966218
a fix for disabling that message can be found. The fix is seen in the last entry of the bug report. It entails creating a file

Code: Select all

# nano /etc/modeprobe/d/iwlwifi.conf

and then entering the following content

Code: Select all

options iwlwifi enable_ini=N

After saving and exiting nano you will need to

Code: Select all

# update-initramfs -u

This should disable those messages from appearing during startup. Worked for me. Hope others can use this information.

EDIT: There is an error in the following code and was pointed out by @mjx

Code: Select all

# nano /etc/modeprobe/d/iwlwifi.conf

It should have been

Code: Select all

# nano /etc/modeprobe.d/iwlwifi.conf

I plead FAT FINGERS.

EDIT 2: Another user pointed another FAT FINGERS error. Should be

Code: Select all

 nano /etc/modprobe.d/iwlwifi.conf

I need to pay more attention to my typing. Thanks to @Vrayden

Thanks for posting this -- it worked for me.

Happy to be of help.

Thank you for help.
found a slight typo in code its

OOPS! Sorry about that. Fat fingers. The slash and dot are next to each other, so I obviously miss typed it and didn't catch my error. Glad you caught my mistake.

@sunrat, okay but I didn't edit my original post. My error was discovered by @mjx and he pointed it out. I guess I can edit my original post to correct my error, as I probably should do. Thanks.

and not # nano /etc/modeprobe/d/iwlwifi.conf

I guess it is "modprobe" and not "modeprob"

Thus:

Code: Select all

 # nano /etc/modprobe.d/iwlwifi.conf 

[ticojohn]

I guess it is "modprobe" and not "modeprob"

Thanks @Vrayden . I corrected the original post.

[bedtime]

Worked perfectly for me. Thanks!

I just did a completely new Debian 11 net install, and that error didn't pop up, so I'm thinking maybe they fixed it?

As root you need to

Code: Select all

# nano /etc/modprobe.d/iwlwifi.conf

Once the file is opened you can then add the prescribed line

Code: Select all

options iwlwifi enable_ini=N

Then press

ctrl o

to save the changes
Once changes are saved press

ctrl x

to exit nano
While still logged on as user

Code: Select all

# update-initramfs -u

Log out as user, close the terminal and reboot. The changes should take effect.

Indeed they should, so long as you type /etc/modprobe.d/iwlwifi.conf and not "modeprobe" as you've again posted.
Funnily enough I've often misread and mistyped modeprobe instead of modprobe myself; easily done.
Anyway, many thanks for the post; I got the firmware failure notice on my ancient Acer Aspire One netbook so I'll now be able to get rid of it.

DARN IT! I just copied and pasted my original typo error. I will edit that post. Thanks @kedaha

Problem when using:

Code: Select all

options iwlwifi enable_ini=N

A note when trying to apply this solution to Debian 12 Bookworm. Instead of using "N" to avoid loading the binary, it is necessary to use "0", as it currently represents "N", which would be the symbol to make it false or not.
So it would look like this:

Code: Select all

options iwlwifi enable_ini=0

[lookus]

for you looking a solution for this, be careful!
if you keep reading the bug report provided by op, near the end you will find a warning near the end (Message #118)
where someone (Francois Marier) warns about the effects on newer firmware (version 66 and above) refusing to load and even lockin on versions 74 and above!
and the proposed solution is to just ignore those warning by now.
you've been warned
