[Bug 276990] Re: iwlagn causes kernel panic on 802.11n wifi

[Mozg]

I do experience kernel panic when using 802.11n router. I have tried the
following, but crashes are still there:

1. disabled 802.11n by using options iwlagn 11n_disable=1
2. installed backports (linux-backports-modules-intrepid-generic, linux-backports-modules-intrepid and linux-backports-modules-2.6.27-7-generic)

I did notice that with backports module my connection becomes somewhat
unstable. I would associate and authenticate with the AP, get the IP
address through DHCP, however, I can't ping anything. If i run as root
ping -f -s 65507 <router ip>, after about 10-60 seconds I would get the
connectivity and wireless seems to work until either a kernel panic or a
disconnect.

I have taken a picture with my cam of the console screen with the last
part kernel panic screen, which is attached to this email.

My laptop is Lenovo T61p 6459CTO with Intel 4965 abgn card.

My system is (latest updates):
lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 8.10
Release:	8.10
Codename:	intrepid

uname -a
Linux finka 2.6.27-7-generic #1 SMP Tue Nov 4 19:33:06 UTC 2008 x86_64 GNU/Linux

nothing interesting is shown in kern.log at the time of the crash

Hope the information helps to determine the problem
