[ath9k-devel] kernel panic possibly related to ath9k

[MadLoisae at gmx.net <MadLoisae@gmx.net>]

Hi Guys,

since a few weeks I am using an Atheros based WLAN PCMCIA-card as AP in 
my linux-gateway.
The only client for this network is at the moment a Nokia E72, I am 
using hostapd in version 0.6.10, I have a WPA/WPA2 PSK encrypted network 
on channel 2 configured.
About two times a week my box crashes, now I have removed the panic=30 
out of my kernel command line and captured an panic (also attached here, 
but I don't know if the attachments work trough the mailing list): 
http://cableguy.no-ip.com/Files/panic.jpg

I think the panic is caused by the ath9k driver.
I have attached my kernel config and my dmesg-output from my last boot, 
I am using kernel 2.6.35.4 on debian lenny.
Hardware is a Via Nehemiah CPU with Via CLE266 chipset, 1GB RAM, CF and 
HDD (both on secondary IDE channel), DVB-Card (Terratec Cinergy 1200 
DVB-C) and WLAN-Card (Atheros AR4516) in PCMCIA-Slot. I am using two of 
the 4 onboard Realtek-LANs, I do not use the onboard soundcard.

The kernel-taint is caused by vmware-server running on this machine, 
here is also my lsmod:

I am familar with applying kernel patches, but I am not able to program 
anysth. :-/

Thanks for any help!

best regards
