Description:

I've stared a thread about this problem here: http://bbs.archlinux.org/viewtopic.php?id=44703

In a nutshell, aireplay-ng played nice with the Arch kernel for a while, but something changed in the more recent kernel versions, and as of now, aireplay-ng causes it to panic when it tries to inject. This problem occurs on my Ubiquiti A/B/G 300mW CardBus card running the Atheros chipset, but apparently this issue relates to all Atheros cards based on information from the aircrack-ng website: http://aircrack-ng.org/doku.php?id=troubleshooting The link states: "There are quite a few problems with some versions of the Linux 2.6 branch (especially before 2.6.11 was released) that will cause a kernel panic when injecting with madwifi. Also, on many 2.6 kernels enhanced RTC support is just broken. Thus, is it highly recommended to use either Linux 2.6.11.x or newer."

Putting this under the "Kernel" category because aireplay-ng can still function fine with different kernel variants.

Additional info:
* Aircrack-ng version 0.9.2-2
* Kernel version 2.6.24.3-1
* Using Arch x86_64

Steps to reproduce:

Run a command similar to "aireplay-ng -1 0 -e teddy -a 00:14:6C:7E:40:80 -h 00:0F:B5:88:AC:82 ath0" on a WEP-protected network with an Atheros-based card using the software versions above.
This task depends upon

you shoult try the kernel from testing it has rtc disabled and jsut uses the new subsystem
Comment by Tobias Powalowski (tpowa) - Saturday, 08 March 2008, 18:03 GMT
now you can also try the one from core

I just tested the one from core. It authenticates to the network with aireplay-ng, but when it tries to associate, it panics. I'm going to try the kernel from testing now, if it's not the same one!

It is :P Thank you so much for your help though! Any more ideas on what I could try?

Found the problem, this lies with the version of madwifi that is in stable. I installed madwifi and madwifi-utils from testing and everything works 100%.
