kernel crash during suspend using iwl3945 driver 1.2.26k on ubuntu hardy

Hello!

I'm using Ubuntu 8.04 with compiled 1.2.26k linux wireless driver for 
iwl3945 network card on my hp6710b laptop.
Script during suspend trying to remove the iwl3945 module and I receive 
kernel crash.
This is repeatable. I attached screenshot of kernel stack. Has somebody 
of iwl3945 developers can look on it?

Greets and regards,

Hello!

I applied the patch but unfortunately still I have a kernel crash.
Look at the screnshoot, stack looks little different:

http://ksi.mikronika.com.pl/~karol/P1180998_s.JPG

Tests I performed with
http://linuxwireless.org/download/compat-wireless-2.6/compat-wireless-2.6.tar.bz2 which
is
compat-wireless-2008-08-06 and git-describe v2.6.26-rc9-14214-g9cb3010
and compat-wireless-2008-07-25 and git-describe v2.6.26-rc9-14207-ga520bdb
with the same result...


Thanks and Regards,
Karol Szkudlarek

Please see if 2.6.27-rc kernels fix this problem. The wme_qdisc stuff is
removed in .27.

Hello Zhu!

It will be tough to see in 2.6.27-rc kernels beacuse I use Ubuntu 8.04 =
LTS
which uses 2.6.24 linux kernel. :-(

The Ubuntu team has a 2.6.27 kernel available. To quote the text of a 
message in a BCM4306 thread "1)  If you are comfortable installing 
packages on your own, the linux-image-2.6.27-* package is currently 
available for you to install and test."

There is a Hardy package for the 2.6.27 kernel at

http://ppa.launchpad.net/timg-tpi/ubuntu

It is currently based on -rc5. I'll be updating it throughout the .27
development and stable cycle.

I would like try 2.6.27 so today I checked=20
http://ppa.launchpad.net/timg-tpi/ubuntu/dists/hardy/main/binary-i386/P=
ackages
and I don't see any 2.6.27 packages...

Second question: do you precompiled also all modules? I need them to=20
perform an upgrade and got the running system.

I found I could not have 2 packages with the same name but different
versions in one PPA, so I moved the 2.6.27 package to the kernel team
PPA at:

http://ppa.launchpad.net/kernel-ppa/ubuntu

Sorry for the confusion.
