 |
|
I'm getting the following when attempting to do a modprobe ath_pci on the new madwifi-ng driver:
| Code: | kernel panic not syncing ifmedia_set
|
Some info on my system:
| Code: | # uname -a
Linux serv 2.6.16-gentoo-r9 #1 SMP Sat Jun 24 13:27:33 PDT 2006 x86_64 AMD Athlon(tm) 64 Processor 3000+ GNU/Linux

The last three grep are for kernel features required by the madwifi driver. I have attempted unmerging and remerging the driver.
On a side note, module-rebuild is still reporting the old madwifi driver somehow:
| Code: | # module-rebuild list
** Packages which I will emerge are:
=net-wireless/madwifi-driver-0.1_pre20050420
=media-sound/alsa-driver-1.0.11
|
I don't know if I can fix that in module-rebuild. The reason why I needed to upgrade the madwifi was I did a compiler upgrade (followed the compiler upgrade guide) followed by a kernel upgrade (followed the kernel upgrade guide). I've remerged both madwifi and alsa and only alsa has successfully worked while madwifi still kernel panics.
I've tried both the marked stable version of the madwifi-ng as well as the latest ~amd64 masked version with the same kernel panic.
I'm guessing there's just one thing that's screwing things up but I don't have any good ideas on where it is. Everything was working on the very old driver (which no longer is supported by gentoo) minus a few annoying bugs in the driver itself. |

Instead of using the ebuilds in portage I went ahead and downloaded the current revision (trunk 1650) from the madwifi SVN by following the download instructions here:
http://madwifi.org/wiki/UserDocs/GettingMadwifi
You can then follow the first time how to located here:
http://madwifi.org/wiki/UserDocs/FirstTimeHowTo
Of course you will want to make sure your kernel and hardware meets the requirements prior to compiling and installing by checking the for the following page:
http://madwifi.org/wiki/Requirements
It should be noted that if you want to use the card in master mode (as your own access point), that you append to your modprobe the autocreate setting by doing something like:
| Code: | | modprobe ath_pci autocreate=ap |
If you want to use wep encryption, make sure the wlan_wep module is loaded as well:
| Code: | | lsmod | grep wlan_wep |
If not, load it:
From there, you should be able to use the normal gentoo net or wireless scripts to configure the ath0 wireless interface or through using iwconfig at the command line.
Once everything is working as you expect, you can add the modules you loaded with modprobe to /etc/modules.autoload.d/kernel-2.6 by doing something like:
| Code: | echo "ath_pci autocreate=ap" >> /etc/modules.autoload.d/kernel-2.6
echo "wlan_wep" >> /etc/modules.autoload.d/kernel-2.6
