Thanks for sharing this Philip. I was surprised to see that firmware for NICs are meant to be added in this kernel config option. I thought that this config option was only for the video card firmware ... # cat /usr/src/linux/.config | grep EXTRA_FIRMWARE CONFIG_EXTRA_FIRMWARE="radeon/R600_rlc.bin radeon/R700_rlc.bin" CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware/" In my /lib/firmware I have: # ls -la /lib/firmware/ total 1448 drwxr-xr-x 5 root root 4096 Sep 14 2012 . drwxr-xr-x 14 root root 12288 Mar 31 09:26 .. drwxr-x--- 2 root root 4096 Feb 4 2012 b43 drwxr-xr-x 2 root root 4096 Sep 14 2012 intel-ucode -rw-r--r-- 1 root root 1451687 Sep 14 2012 microcode.dat drwxr-xr-x 2 root root 4096 Dec 31 09:58 radeon and from dmesg I can see that all of these get loaded *without* being defined in the CONFIG_EXTRA_FIRMWARE= ... On this box in any case I do not have sys-kernel/linux-firmware installed, but have installed x11-drivers/radeon-ucode for the video card and net- wireless/b43-fwcutter for the wireless NIC. Are you saying that the correct way to go about this is to uninstall these packages and instead define the firmware in the kernel in CONFIG_EXTRA_FIRMWARE= ??? I'm confused. :-/ PS. I'm currently running kernel-3.7.10-gentoo. -- Regards, Mick
