Linux chakra-pc 3.9.2-1-CHAKRA #1 SMP PREEMPT Sun May 19 21:38:45 UTC 2013 x86_64 GNU/Linux
This confirms that you are using 3.9.2-1 version of the Linux Kernel.
It also explains that you have a x86_64;(a 64-bit computer architecture)
Indeed you are running Chakra Linux and the Codename is "Benz"
As teckk said;
This error looks like a place to start.
The current version of the kernel is 3.11.4
The error messages states that "madwifi: requires<3.10"
So; this tar is available:
3.10.15.tar.xz is an xz archive that is 69.8 MB
Only Teckk can advise you on which version of the kernel you should use. This is not my area of expertease.
