[SOLVED] boot message"firmware:failed to load brcm/BCM43142"

[hughparker1]

DELL Inspiron 15 3543 (3000 Series)
5th Generation Intel Core i5-5200U Processor (3M Cache, up to 2.70 GHz)

I have installed Debian 8 and the wireless adapter Broadcom Corporation BCM43142 802.11b/g/n wasn't recognised so I used LAN cable and completed the install.

I followed instructions from this link... https://wiki.debian.org/wl and managed to get my wireless recognised and is now working correctly.

I did notice that even after wireless is working ok, I continue to get an on screen message during boot process....

Code: Select all

    Loading, please wait...
    fsck from util-linux 2.25.2
    DEBIAN: clean, 130848/3842048 files, 1060212/15360000 blocks

    [  16.433222] Bluetooth: hci0 command 0x1003 tx timeout

The message isn't a big problem as my wireless is now working ok, but I wonder what causes it and is there any way to stop it being displayed, if that was possible.

Do you need the BlueTooth functionality on that device?

startpage.com offers plenty of other options but I can't be bothered copypasting the links...

thanks for feedback, I don't need the bluetooth, never used it to be honest.

I had a look online and although there were several hits for BCM43142, they all looked at getting the adapter to work. My wireless is now working ok, but I just get this boot message "firmware: failed to load brcm/BCM43142" every time I switch on laptop. It's not a big deal, I just wondered if there was a way to stop message from being displayed since adapter is now working ok.

I don't need the bluetooth, never used it to be honest.

Try this:

Code: Select all

# echo -e "blacklist bluetooth\nblacklist btusb" > /etc/modprobe.d/bluetooth.conf

thanks for reply.

can you tell me what this command does, so I know what to expect.

also can it be reversed in the future?

[Head_on_a_Stick]

can you tell me what this command does

It creates a configuration file at /etc/modprobe.d/bluetooth.conf that blacklists the "btusb" & "bluetooth" modules and disables bluetooth functionality at the kernel level.

Reverse it using:

Code: Select all

# rm /etc/modprobe.d/bluetooth.conf
# modprobe -v bluetooth btusb

thanks for explanation, will this eliminate the boot message firmware failed to load?

[Head_on_a_Stick]

will this eliminate the boot message firmware failed to load?

There's only one way to find out...


I do not have that hardware; this is a shot in the dark on my behalf.

If it doesn't work, just delete the file (I should have posted that originally, sorry).

Thanks again for your help on this. I did hesitate a litle but decided to give it a try since you have provided an undo option

I ran the code as you suggested...

and rebooted laptop. the "failed to load" message is no longer displayed....
