[ath9k-devel] AR5008 hanging computer

[James Grossmann]

I have a linksys wpc100, which contains the ar5008 chipset.  After a
little while of use, It hangs the computer so that almost nothing
responds.  I have found that if I hold the power button down until
just before it would force a poweroff, I can usually get it to
respond.  I have it installed in a thinkpad x24 (pentium III, so
there's no multi-core/processor), and using ndiswrapper when I'm not
trying to overcome this problem.  I have also had the same problem
when I had it installed in a t23, a very similar pentium III laptop.
I am running kubuntu 9.10 with the backports modules installed, I know
they aren't the newest, but I've tried the
I have followed the instructions to debug the problem, but I could use
some more specific ideas of what to debug, because with all debug
options on, over a couple of days, I produced a 1.2 gb debug file.  In
perusing the file, I found a few anomalies that were obvious to the
casual observer...me, but which may or may not tell us anything, I
will post them below.  I also note that there seems to be a lot of
authenticating/deauthenticating going on, although that could have
been from the ndiswrapper driver.
Thanks,

James

It did this similar thing a couple of times around one of those hangs.
the Authenticating/deauthenticating looks like this, I removed the
module with the debugging enabled here, and immediately upon using the
card again later, I start getting the authenticating/deauthenticating
notes.

I suggest that you give the exact kernel version, as a courtesy to those
not running kubuntu 9.10.

You can use "dmesg -c" to erase the kernel log.

Getting kernel log from /var/log is not a good idea.  Please use the
dmesg command.

You can use less debug options to get something of manageable size.  You
can use sed to remove the timestamps (I don't think they are very useful
for this particular problem) and use lzma to compress the log:

dmesg | sed 's/^[^]]*] //' | lzma >kernel.log.lzma

I was hoping you could provide possible debug options I could look at,
with all the debug options on, I was filling dmesg's buffer in less
than 1 sec, not enough time to catch it when it stopped and I had to
intervene.  Kubuntu 9.10 is using the ubuntu 2.6.31-19-generic and the
2.6.31-20-generic kernels.
Thanks!

I know /var/log/syslog can hold more kernel message than dmesg. Any other disadvantage?

That's true.  But syslogd can omit low-priority messages from the
kernel.  Irrelevant logs from other software can be present.  The
timestamps are rarely needed and take extra space.  They also don't
compress well.  The is no convenient alternative to "dmesg -c" to clear
the log and start over.  I would not recommend clearing the system log
like that, as it can contain important information from the userspace,
such as break-in attempts etc.

If the log buffer overflows, perhaps it's a good idea to disable
irrelevant debug options or to stop debug output as soon as the error
condition occurs.  If case of hangs, serial console could help.

I'm also sorry about that, on the other hand, there are many schools
of thought on answering posts, but I don't want this to be a
discussion of that.
I would just like to get some ideas of what I can debug to get some
answers.  Out of curiosity, is there a way to do a continuous
recording of dmesg to a serial console?  These hangs occur regularly,
but very unpredictably and at fairly long intervals.
Thanks,
James

What's really needed is what happens immediately before the hang, so the
history is not really interesting.

I would try to enable more debugging options in the kernel. It could
help detect the problem earlier if it's a software problem, such as
memory corruption.

Use netconsole but you need two machines.

I would never recommend using netconsole to debug a hang in a network
driver.  Chances are too high that the hang will block the network stack
and prevent the most interesting data from leaving the system.

Besides, it's one thing to debug something that is easy to reproduce and
that is known to show up on the netconsole.  It's another thing to debug
something that may not appear on any console after hours of waiting.

[ath9k-devel] 802.11n in Ad-hoc mode

[Jónatan Muñoz]

Hi all,

I am interested in the current status of 802.11n support under ad-hoc mode.

Do you know anything?

Are there some deadlines or plans implementing ad-hoc mode in 802.11n?

I have AR928x Atheros chipset.

Thanks,

John

Here is a dmesg containing a hang, the dmesg even notes that there was
a soft lockup.
I hope this helps, thanks in advance!

I should note that I am now using a different computer with that card,
again, kubuntu, but using the 2.6.32.8 kernel available at
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32.8/.  I have also
updated to the latest linuxwireless compat drivers.
Thanks again!

Sorry for delay.

Assuming the the EDX register holds the chip register number number, it
looks like a CPU lockup when AR_ISR_RAC is read in ath9k_hw_getisr().  I
have no idea how to work it around.  Maybe somebody with access to
Atheros specifications could help?

Hi,
	I have this problem as well. 
Hardware is:

Atheros Communications Inc. AR5008
Atheros AR5416 MAC/BB Rev:2 AR5133 RF Rev:81

Kernel:Linux 2.6.32.7 #2 PREEMPT Thu Feb 4 14:19:02 PST 2010 i686 GNU/Linux

driver is supplied with kernel.

I used to think it had to do with returning from suspend to ram.
Because on return it will never initiate a scan for new AP's.
But it hung the other day wen the machine was left running and moved
to a new location, scan worked like it should when the lease expired
and froze the machine.
The panic can be caused by starting wpa_gui and requesting a scan.
Sometimes it works, some it crashes the machine. I'll see if I can 
find a backtrace, or make one.

Thanks, mark

That's the PCMCIA subsystem, not ath9k.  We could suspect ath9k to cause
it if it was immediately after ath9k was loaded, but there were other
things going on after the ath9k initialization.

Sorry about that Pavel, this was a boot hang after a crash caused through
an ath9k hang. I thought it was the same problem, but the card is
mini-pci, so shouldn't have to do with yenta.

I can cause the hang every time if I boot the machine with no
configured AP available. I have rebuilt ath9k with debugging and configured
kdump. I was just trying to make a core dump by unplugging the AP.
This time it took 55 seconds for the machine to hang. I say hang not crash
since after two or so minutes (not knowing what should happen with a kdump
kernel, there is no "stop-a" like on sparc) it came back. 
I have included the traces from dmesg. 
I can also pass debug mask or I guess force a dump, which ever is
more useful. The driver will also not scan for APs after a suspend to ram.
Booting the machine in an area without wifi will cause a hang every time,
even just booting to a cli login prompt. 
Time frame is 30 to 120 seconds.
I suppose now it would come back if an AP were turned on. 
Logging in as root and rmmod ath9k, problem goes away. 
The driver/card will run for weeks if associated. 

Is it possible this is a hardware issue?

Thanks, mark

It looks like a hardware issue, but maybe it can be worked around.

I believe the register number is in DX.  Register 0x8258 is
AR_SLP_MIB_CTRL, and it's indeed being read in ath9k_hw_procmibevent().
Somehow reading that register causes a CPU lockup.

An easy workaround would be to comment out this line in ani.c:

if (!(REG_READ(ah, AR_SLP_MIB_CTRL) & AR_SLP_MIB_PENDING))

Leave the new line so that the register is cleared unconditionally.

Yesterday I experienced a panic when I put some load on my 5008 card.

I'm using wireless-testing as of Mar 7, and in general this is a
clear improvement when compared with code as of Feb 1. Thanks to
Felix for great work on the driver!

Unfortunately I don't have a backtrace since I was in X on my laptop,
and I also haven't been able to reproduce the issue. :\

Will post again, possibly in a new thread, if I can make it happen
again. Previously I have not been using .11n much, but now I was, 130
or 170Mb connection and 70/70 link quality, I was a few meters away
from the AP.

I've been running a 2.6.33.1 with this one line modification and I haven't
seen a single system hang anymore. My wlan device is sold as D-Link DWA-645:

03:00.0 Network controller: Atheros Communications Inc. AR5008  
Wireless Network Adapter (rev 01)
	Subsystem: Device 07d1:3a09
	Flags: bus master, 66MHz, medium devsel, latency 168, IRQ 11
	Memory at 4c000000 (32-bit, non-prefetchable) [size=64K]
	Capabilities: [40] #80 [0000]
	Kernel driver in use: ath9k
	Kernel modules: ath9k

Without this patch I would get a ath9k based hang in a 3-4 days time  
eventually.
The hang could be solved usually by unplugging and re-plugging the  
pcmcia card.

Hmm, it looks like my problem might be related to yours as well.

My lspci entry is:

03:00.0 Network controller: Atheros Communications Inc. AR5008
Wireless Network Adapter (rev 01)
	Subsystem: Device 07d1:3a09
	Flags: bus master, 66MHz, medium devsel, latency 168, IRQ 11
	Memory at 4c000000 (32-bit, non-prefetchable) [size=64K]
	Capabilities: [40] #80 [0000]
	Kernel driver in use: ath9k
	Kernel modules: ath9k

and dmesg reports the hardware as:

phy0: Atheros AR5416 MAC/BB Rev:2 AR2133 RF Rev:81 mem=0xf8300000, irq=11

My problem is that the laptop will eventually hang sooner or later
to a complete halt if there is some traffic going via the wlan
pcmcia card. The hang can usually be recovered by ejecting the card
from its slot.

One of the logs contains the following information:

Karmic uses 2.6.31 which has already reached the end of its
development. You will no longer see stable kernel releases based on
2.6.31.y kernels so best is to upgrade. ath9k had a large number of
patches which did not get merged into 2.6.31 [1] which should have,
which is why we worked hard for 2.6.32 to ensure all regressions/fixes
are propagated to stable.

Karmic ships lbm though and that uses the 802.11 bits from 2.6.32
which should be good.

Unfortunately, I completely forgot to mention the very important fact that
in my understanding the "standard" karmic kernels ie. 2.6.31.x worked
quite ok compared to the compat-wireless versions included in  
linux-backports-karmic etc etc. In other words, my problem tends to be  
that the latest
ath9k versions are having some problems, while the older 2.6.31 seem to
be working without hangs in my case (not counting connection drops  
every once in a while). Sorry, for turning this upside down.

Although, I've been way too busy with other important matters, I'll  
try to find the last "properly" working kernel by using the GIT kernel  
versions, so that I can be sure about the used versions.  
Unfortunately, this laptop is quite slow and the hang doesn't happen  
immediately (might take 1-2 days, but still it will always happen with  
newer versions of the ath9k drivers). Anyway, it's very good to know  
if these problems are more common among cards based on these chips or  
is this just a rare case.

This particular card was sold as D-Link DWA-645.

I'll report back after I've done some more testing in order to get  
more facts about different ath9k driver versions.

You'll want to read:

http://wireless.kernel.org/en/users/Documentation/Reporting_bugs
http://wireless.kernel.org/en/users/Documentation/Fix_Propagation

That should get you to test and report against the right thing.
