Subject: [iwlagn] System crash on dell e6420 using iwlagn from kernel-git

Hi everyone,

I'm currently testing out the git repository of the linux kernel.
Unfortunately my system (Gentoo) always crashes shortly after the
Networkmanager service is started. Not starting the service or using the
radio killswitch is the only possibility to get the system up. I already
tested versions 0.8.4 and 0.9rc3 of Networkmanager resulting in the same
error. This behavior came up with using the git-Version of the kernel
whereas it was working in the 3.0.x releases.
The really bad news is that I cannot send a detailed trace with this
message as the relevant parts of the log message are gone due the
following hardreset. But luckily once a trace remained, which is from
the older rc1 but still describing the same problem. Unfortunately no
debugging symbols were active when this trace was generated.
I've also attached some information about my system.
I hope you can help me out. Thanks.

Best regards,
Alexander Diewald

Hi Alex,

I see that there's a null pointer dereference in one of the iwlagn functions.

Can you point me to the kernel tree you're using?

Thanks,
Meenakshi
