iwlwifi module hangs

[camille]

Hello,

Using Mageia 2 with the following configuration:

Code: Select all

Linux localhost.localdomain 3.3.8-desktop-2.mga2 #1 SMP Mon Jul 30 21:35:06 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
iwlwifi         : Intel Corporation|Device 088e [NETWORK_OTHER] (rev: 24)


I had to set a few options in modprobe.conf to have it work properly:

Code: Select all

options iwlwifi 11n_disable=1 bt_coex_active=0 power_save=0 swcrypto=1

However, I use to suspend the machine when travelling from work to home and back. After 2 to 3 days of this treatment, the iwlwifi module doesn't work anymore.
I get in the log:

Code: Select all

iwlwifi 0000:02:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0xFFFFFFFF

There's no way I can unload the module.

When trying an rmmod I get the following errors on dmesg (see attachment)

Any idea?

Camille.

in your dmesg there is a driver crash...

it is better to report this kind of faults to the driver developers,
usually you can find them here
http://www.intellinuxwireless.org/
but the site seems down in this moment

For information, I definitely solved the problem by adding: the following in /etc/pm/config.d/modules:

SUSPEND_MODULES="iwlwifi"

It even works better than before, reconnecting me automatically to the available wifi network.
I suggest that should be added to the default configuration.

I suggest that should be added to the default configuration.
