I have tested on the server with the latest wireless-testing the past days
(2.6.28-rc9-wl). The wireless-testing looks somewhat more stable then the
compat-wireless.
I have also installed the netconsole module to watch any kernel prints. After
running hostapd (v0.6.6) from command line the AP is up-and-running. Then if I
connect with the laptop (tested it with kernel .26 and .28 on the laptop) I
get a connection and can start a browser en explore the internet. If I start
a second session (Kmail or second browser) the
server hangs within a minute. Leaving again no trace on the console,
hostapd-log or netconsole.
Only way to reset the server is switch off the power.
Its very frustrating because no information or what so ever can be found.
If I connect an internet radio (Musicpal) to the server there is no problem.
It stays stable for hours. If I also connect the laptop and start a browser
the server hangs again within minuts.
Its looks like if there is a second connection been set up the server hangs.
Anyone any clue how to investigate this??
Thanks,
Willem

I have narrowed the problem down to the number of connections setted up in a
short time.
If a system (notebook, internetradio or what so ever) setup a number of
connections is a very short time (couple of seconds) the server crashes.
If I start Kmail on the notebook (with 5 mailboxes) the server crashes within
seconds. Its always reproduceble. If I change the broadcast on the
internetradio fast (for example 3 time with seconds between them) server
hangs.
All the server hang ups dont leave a trace in log or console what so ever.
Hope this gives any additional information.

Willem

Just to make sure I understood this correctly.. Does this happen with
just a single association station (your laptop)? What are you referring
to with a "session"? Just another program using network (i.e., no new
wireless associations, etc.)? As far as the ath9k driver is concerned,
new applications (e.g., new TCP connection) should not really matter
much.. If you have IEEE 802.11n enabled, could you please run a test
with it disabled to make sure this is not related to frame aggregation?
As far as getting any output from the system is concerned, the next step
could be to see if NMI watchdog would be able to provide any help.
Please take a look at Documentation/nmi_watchdog.txt in the kernel
source code and see if you could use that on the AP to get some output
when the system hangs (running without X on console to make sure you see
the output).

Hi Jouni,
Yes you understood correctly. Only a laptop, start a browser then start Kmail
over the same wireless connection. Then it hangs. This is always
reproducable. There are also other sorts or hangups (for example when
starting hostapd, but that is not always reproducable when it happens).
I will try today the watchdog-suggestion. Hope that it will provide some help.
To be continued....
gr,
Willem

I have no 802.11n enabled, nor X.
This means I think the system halted hard 'hlt-instruction'
Any further suggestion? I am little bit hopeless now. I have placed the PCI

Some additional information:
I have booted the server at approx 16:00. Hostapd was started at boot-time.
After 5 hours without any connection from any computers the server hangs.

Just as a data point, I'm running master mode with ath9k on 64bit with
multiple clients and have no problems. Perhaps it's hardware version
related? Here's the info for my system:
kernel: 2.6.28-gentoo
compat-wireless-2.6: cedd75beb269e2b559a5174ee628ebd01f63a4040
wireless-testing: fd1dae5fbc7a260b0ddfab7d4939a766a82ef3f3
hostapd: 2c04820d80b5c489576cb735c3be8f026a035a5b
I have 80211n enabled for my device with this config:
ht_capab=[HT40-][SHORT-GI-40][DSSS_CCK-40]
my device:
Network controller: Atheros Communications, Inc. AR5416 802.11a/b/g/n
Wireless PCI Adapter (rev 01)
phy0: Atheros AR5416 MAC/BB Rev:2 AR2133 RF Rev:81:
mem=0xffffc20000060000, irq=17
Currently I'm using my ps3, axim, laptop, and a netbook at the same
time, and have no disconnects. Any additional testing I could do that
might help you out, or more information I could provide you?

I have tested today with the latest wireless testing 2.6.28-wl and tested with
WPA and without WPA. It didnt make any difference.
I am getting pretty hopeless now. Because nothing seems to work or give any
progress.
This is the hostapd log:

Did some futher testing to exclude problems....
The wlan0 and eth1 are both part of a bridge. I have removed the eth1
interface so the the eth1-driver cannot interfer with the ath9k driver.
Also no result. The server still locks.
What is the right way to combine the eth1 and wlan0 into a bridge. Do I even
need a bridge? The hostapd.config says I must define a bridge when I use the
nl80211driver interface.
The bridge has an IP adress, wlan0 and eth1 are in the same subnet.
When hostapd is started I have some error-messages. Dont know if they can
hurt...
Failed to set CTS protect in kernel driver
Failed to set Short Slot Time option in kernel driver
Could not set preamble for kernel driver

I use gentoo's init scripts, but my wlan0 and eth0 are both in a bridge
(br0) and it works fine. I don't get the CTS, Short Slot Time, or
preamble kernel driver errors. Perhaps you need to comment out a few
lines in hostapd.conf?
# preamble=1
and I have:
rts_threshold=2347
I'll send you a direct e-mail with my .config and hostapd-wep.conf files
to help with debugging.

I have used your config files for hostapd. Only change I have made is comment
out the CONFIG_LIBNL20 because I have no lib for the debian lenny distro. But
I dont think that will hurt much.
The error messages are gone.
However the system hangup still occurs. It looks like a DMA - ath9k related
problem.

Hi,
I have tested with the latest kernel 2.6.27.10 and compat-wireless 22-12-2008.
I have a dual core system (Intel(R) Pentium(R) 4 CPU 3.00GHz) and use hostapd
0.6.6.
I have build the kernel, compiled the compat-wireless and did a make install.
Make unload didnt work because some drivers were in use (mac80211).
First problem arises, a rmmod ath9k hangs the kernel. No message of what so
ever in the log or to stdout.
Rebooted the system (hostapd still disabled). Iwconfig shows:
wlan0 IEEE 802.11bgn ESSID:""
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=27 dBm
Retry min limit:7 RTS thr:off Fragment thr=2352 B
Encryption key:off
Power Management:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
If I start hostapd (by hand or from init.d) the kernel hangs with no trace of
such thing. Hostapd shows in stdout (with -dd):
Configuration file: /etc/hostapd/hostapd.conf
ctrl_interface_group=0
Opening raw packet socket for ifindex 1688

Passive scanning not supported
Flushing old station entries
I have tried in the past several kernelversions and compat-wireless versions
and all give the same problem.
So I think it is hardware (system) related and ap-mode.
How can I trace the problem? Default I get no entries in any log.

Can somebody provide some help. I am struggeling to get the card into ap mode.

I've never tested this with compat-wireless, but the wireless-testing
version seems to be working fine in my tests.

Would you happen to have another host available for storing the logs? I
have been able to receive debug messages from most crashes with
netconsole (see Documentation/networking/netconsole.txt).

After it fails to unload do
lsmod | grep mac80211
to see which ones are still loaded and depending on mac80211.

Please do:
modprobe -l ath9k
modprobe -l mac80211
To ensure the right drivers are loaded.
lsmod | grep mac80211
lsmod | grep ath
