kernel panic upon dhclient usage with some router (occurs also with some other commands)

Description (Last modified by mrenzmann)

I am using the madwifi version shipped with Ubuntu Gutsy

I got a kernel panic when using dhclient on a certain wifi network.

I use the amd64 version of Gutsy with an Atheros AR5005G wifi card.

The router (and dhcp server) on the network causing the kernel panic seems to be called "Broadband Router" in its configuration file.

For now I don't know wether it is due to the madwifi driver not handling correctly some maybe not conventional ommands the router may sends or maybe dhclient or I don't know what.

here are some hopefully useful files information and files :

uname -a result :

Linux chameau 2.6.22-9-generic #1 SMP Fri Aug 3 00:20:35 GMT 2007 x86_64 GNU/Linux

There are also two other way to get the kernel panic :

  1. I can configure the interface manually, and then if I try to access the router it crashes (pinging is okay but logging into it crashes just after entreing the user credentials)
  1. I can also configure the interface manually and if I try to access the DNS server it will also crash.

Please test if the problem still exists when using trunk.

Replying to mrenzmann:

using trunk.

Trunk is the svn version ?

If so is there a way to download it under windows and then compiling it under linux (right now I have some troubles connecting to internet with linux)
