Hi Forum,
my problem is as announced above.
Code:

modprobe iwlagn

FATAL: Error inserting iwlagn (/lib/modules/2.6.38-gentoo-r6/kernel/drivers/net/wireless/iwlwifi/iwlagn.ko): Unknown symbol in module, or unknown parameter (see dmesg)

I think dmesg wants to tell me, that there is a problem with the ucode, but that is installed on the laptop
Code:
emerge iwl6000-ucode

Code:

This error usually means that your kernel and module don't match. Possibly you changed something in the config from N to Y but did not rebuild/install the kernel afterwards.

Verify with "uname -a" (build date and time) that you are running the correct kernel.

No thats not it, BUT you pushed me in the right direction.
I wanted to check my grub.conf and found out, that my sda1 (the seperate boot-partion) was not mounted => when ever I copied the kernel to /boo/kernel it remained on the sda2/root-partition and never touched Grub.

Trying to fix that now.

EDIT: yeah fixed; but still no wireless connection and no LED

So do you have wlan0 now or not? "lspci -k" lists iwlagn as kernel driver in use for your wireless? "ifconfig wlan0 up" succeeds or returns an error? "dmesg" says what when you run it?

You apparently don't have the firmware installed for the wireless chipset. Install either the net-wireless/iwl6000-ucode or sys-kernel/linux-firmware package.

No matter what package I install, both tell me the same in dmesg.

What I find interresting is the fact, that in dmesg it says

[ 15.051234] iwlagn 0000:03:00.0: request for firmware file 'iwlwifi-6000g2a-5.ucode' failed.


Code:

locate iwlwifi-6000g2a-5.ucode
/lib64/firmware/iwlwifi-6000g2a-5.ucode
/root/iwlwifi-6000g2a-ucode-17.168.5.2/iwlwifi-6000g2a-5.ucode


So it's there and both packages are not finding it

Is iwlagn a module or built-in? Maybe at the time when it loads, there is no firmware present because the root filesystem has not been mounted yet.

It's compiled as a Module. From the helptext I also I got this
Code:

The microcode is typically installed in /lib/firmware. You can         
look in the hotplug script /etc/hotplug/firmware.agent to               
determine which directory FIRMWARE_DIR is set to when the script         
runs.               


But this dir does not exist.

Code:

emerge hotplug
* Messages for package sys-apps/hotplug-20040923-r2:

 * WARNING: The hotplug init script is now gone (dead and buried).
 * WARNING: If you want to load modules for hardware that was already
 * WARNING: discovered at boot time, like the old hotplug init script
 * WARNING: did, then emerge the coldplug package, and add coldplug to
 * WARNING: a runlevel, e.g. # rc-update add coldplug boot
 * WARNING: All firmware loaded by the hotplug scripts needs to be
 * WARNING: moved to the /lib/firmware directory, as the scripts now
 * WARNING: expect it to be in that location.
 * If you still have the file /etc/hotplug/isapnp.rc on your system,
 * please delete it by hand, the file /etc/hotplug/pnp.rc supercedes i



EDIT: I ignored the warning, went with coldplug; started it and now it's working.
LED is on, Hotkey works and I can connect via NetwrokManager.

Just the last question (kinda dumb):
Is it bad, that I use a service that is dead and burried or can I juts stick with it? What's the worse that could happen?

So if you unload and reload the module, are you still unable to bring up the wlan0 interface? Note that genkernel may copy some modules to initramfs and if they get loaded from there, the firmware might be missing.

No I think you misunderstood (or I mistyped or something) it works fine.

I can bring the Interface, connect with it etc. etc.

Only strange thing is, I unemerged hotplug and it still works.

Code:

I had the same problem when I tried to get a Centrino Advanced-N 6205 in my new Thinkpad x230i up and running. In my case, however, emerging the linux-firmware-20120924 ebuild did the job, it contains the iwlwifi-6000g2a-5.ucode firmware file:

http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=tree

Thanks for your posts!
