Hello,
Here is a description of my system :
Linux : 2.6.35-22-generic (on a ubuntu 10.04 LTS)
My wifi card is : 02:00.0 Network controller: Atheros Communications Inc.
AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
"dmesg" outputs about the wifi controller are :
Oct 10 17:28:49 kernel: [ 12.546288] ath9k 0000:02:00.0: PCI INT A -> GSI
17 (level, low) -> IRQ 17
Oct 10 17:28:49 kernel: [ 12.606040] HDA Intel 0000:00:1b.0: PCI INT A ->
GSI 16 (level, low) -> IRQ 16
Oct 10 17:28:49 kernel: [ 12.653486] phy0: Atheros AR9285 Rev:2
mem=0xf8e60000, irq=17
I am using an atheros Wifi Card in ad-hoc mode, I create my ad-hoc network
with two differents ways :
1. Thanks to the following commands :
ifconfig wlan2 down
iwconfig wlan2 mode Ad-Hoc
iwconfig wlan2 essid "Toto"
ifconfig wlan2 up
2. Thanks to the ubuntu network manager "Create a New Network" function's.
The way I use to create the network doesn't matter.
A few minutes after the AdHoc network is created, my system freeze. I have
got the following message in /var/log/kernel :

----------------- END OF MESSAGE ------------------
Of course this message is only the call trace of the wifi driver, all
process running on the system generate a call trace. I am almost certain
that the problem come from the WiFi in AdHoc mode, because if I disable this
feature my system never freeze !
I will try with a newer kernel, but I read all the changelog from the 2.6.35
to 3.0, and I haven't seen any fix about my problem, so I don't think this
bug was fixed...
Any help will be very appreciated,
Best regads,
Adrien BARRAL.
Robopec.

please let us know if this issue occurs in the latest compat build
http://linuxwireless.org/en/users/Download#Where_to_download_bleeding_edge
i just tried the same in my 3.1.0rc8- wireless-testing, no freeze
happened... may be i would have missed something
please disable network-manager(sudo service network-manager stop)
before configuring with command
may be the freeze can occur with the network manager enabled and we
are trying to create an ad-hoc mode
