Subject : Disassociating atheros wlan with 2.6.31 Submitter : Kristoffer Ericson <kristoffer.ericson@gmail.com> Date : 2009-09-24 10:16 References : http://marc.info/?l=linux-kernel&m=125378723723384&w=4 Notify-Also : "Justin P. Mattock" <justinmattock@gmail.com> This entry is being used for tracking a regression from 2.6.30. Please don't close it until the problem is fixed in the mainline.
Going to do a bisect when I get a chance. The issue appeared somewhere between 2.6.30 and 2.6.31 and is still present in 2.6.31.1.
Created attachment 23266 [details] Part of bisect log I tried to do a bisect on the bug but since it only appears after a certain time it was hard to be sure what was good. When reading this bisect log please remember that the bad sections are confirmed while the good ones might be bad (just didnt wait long enough). Hopefully this will atleast shorten down the time for someone doing another bisect.

At the moment I'm seeing two messages 1) No probe response from AP xx:xx:xx:xx:xx after 500ms, disconnecting. 2) wlan0 deauthenticating by local choice (reason=3) I have seen the Disassociating message, but can't remember when. At the moment I'll do a bisect for these two, and then go from there. (maybe I saw the Disassociating message after a while of running the internet off of the card).
I've seen both, although 1. (with disassociating instead of disconnecting) stands for approx 90%. Under usual internet load (casual browsing) it happens after 15-30mins, takes longer if internet isnt active. I run through my 3G modem (ppp0) and allow my gf to use my internet through wireless (wlan0). When I bisected (without using my internet, due to problems) it could take anywhere between 30min - 2 hours before I got that message. On my 2.6.30 kernel I essentially never saw it even after 48hours of uptime.
At the moment ill see if I can do the bisect for: No probe response from AP xx:xx:xx:xx:xx after 500ms, disconnecting. (hopefully I do this correctly i.g. at one point I might have not of waited long enough to see if this fires off and gave a git bisect good, kind of what happened to you)
o.k. I'll try a bisect from 2.6.30 to current. (hopefully I don't get confused with good/bad this time on the bisect)

Still don't understand why this happened, my only guess is something to do with doing the bisect in my own working branch, maybe something went astray...
Created attachment 23313 [details] git-bisected from 2.6.30 to current HEAD. Here's my git log from 2.6.30 to the current HEAD. personally I think it's off by a few due to the inconsistency of this type, hopefully it's in the vicinity of what might be causing these issues. Please look at them and give feedback. If I need to do another bisect let me know(just point out to me what I need to look for with this, since this issue seems to be tricky). below is what git bisect said was the problem (I'm not convinced that it is, but could be wrong). ab1faead50d09165b58c2854997c7205ca9c0d22 is the first bad commit commit ab1faead50d09165b58c2854997c7205ca9c0d22 Author: Johannes Berg <johannes@sipsolutions.net> Date: Wed Jul 1 21:41:17 2009 +0200 mac80211: remove dead code, clean up With mac80211 now always controlled by an external SME, a lot of code is dead -- SSID, BSSID, channel selection is always done externally, etc. Additionally, rename IEEE80211_STA_TKIP_WEP_USED to IEEE80211_STA_DISABLE_11N and clean up the code a bit.

Good work, will give it a go later next week once I get back to my apartment. Atleast we got an area to work with so should be able to pin it down eventually.
Cool thanks, towards the end of the bisect was too tired to start testing single commits to see.(hopefully this gets us in the vicinity though) tomorrow Ill plug-in some single commits to see.
I have the same problem with the b43 driver – can’t get connected more than 1min with a 2.6.32-rc3 kernel (same error), works fine with a 2.6.30.
If you can, I attached my bisect log to the bugreport, thumb through and individually try reverting some commits to see.(was in the process of doing so, but got distracted with other things). If none of the commits listed with the bisect log work. then you'll probably have to do a bisect of your own to see..(shouldn't take too long).
Having the same issue here (ath9k on an Eee 1000HE), just wanted to add that it happens at school all the time, sometimes as soon as I connect (unsecured 802.11g). However, at home I have yet to see it happen (WPA2 802.11n). Hopefully that's useful to someone. I've been trying to track down the source of my wireless problems in 2.6.31+, my rfkill issues seem to be clearing up now, but this is the newest major problem.

hmm.. looking at my bisect-log, seems there was more to it there whats in there now(must have done something wrong with the upload).

hmm.. just threw my old system away on this machine, and threw in a new one. except this time changed No Forced Preemption (Server) to Voluntary Kernel Preemption (Desktop) and set the time freq to 1000 upon loading up and running music/firefox etc.. the wireless/wpa_supplicant kept disconnecting(really noticeably this time). I'll have to try another bisect on this.(the time to recreate this varies from right off the bat, to around 20/30min)
Take a look here: http://bugzilla.kernel.org/show_bug.cgi?id=13807 It seems like that might be helping some people.
hmm, sounds like pretty much same bug as this. I can understand why that patch works, but it doesnt really fix the underlying issue. "ath9k: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x40000020" might be worth looking at. Ive pretty much setup a testground now, so will give it a go tommorow. Justin, please go ahead and bisect and we'll see if we end up at same point (or atleast are).
in the process of doing another. above is the bisect from the other system. keep in mind the recreation of this was way different than that of what I'm seeing now.(could of been the change of the .config, or something else). In any case hopefully I can get somewhere on this, but then again you never know.
Whew I'm just now finishing up the bisect...(took a while). Anyways reverting the commit below that the bisection found fixes the crappy connections that I've been experiencing.(didn't see this drastic of internet disconnects with the other machine because my .config was different i.g. changing No Forced Preemption (Server) to Voluntary Kernel Preemption (Desktop) and changing the timer to 1000 but keep in mind that's just a guess) below is the commit that's breaks my machine, reverting fixes it(but still need to run the machine longer to make sure)and also the bisect log 75e6c3b72b3ab01c47629f3fbd0fed4e6550bf3a is the first bad commit commit 75e6c3b72b3ab01c47629f3fbd0fed4e6550bf3a Author: Johannes Berg <johannes@sipsolutions.net> Date: Fri Jul 31 11:18:13 2009 +0200 cfg80211: lower dynamic PS timeout to 100ms The default of 500ms is pretty high, and leads to the device being awake at least 50% of the time under such light traffic conditions as a simple 1 second interval ping.

o.k. I couldn't wait try to out the internet in the hotel, and the patch. (so I broke down and paid the 12$ for internet)... So far I've been streaming the radio, streaming a movie for over a half hour, and no signs of what I was hitting. I'll try and run this all day to see if there's any disconnects, or anything in dmesg(other than that I think it's o.k.).

This is a post-2.6.31 commit, but this bug is about 2.6.30->2.6.31 regression. Or am I missing something?
All's I know is the bisect pointed me there (you got's me); Although kristoffer, had pointed out that this did not help his issue out! interesting to see if he had finished his bisect,or came closer to finding out what might happening over there.
(In reply to comment #30) > Although kristoffer, had pointed out that this did not help his issue out! > interesting to see if he had finished his bisect,or came closer to finding > out > what might happening over there. So you tracked down a different issue. The original still remains, OK. Kristoffer, was you able to proceed somehow with the bisection?

However I did do a test build on vanilla 2.6.32 and it resolved my issues with disconnecting wlan0 it seems. It did introduce some other issues though (my mobile internet connection is now flaky). I will try and do a bisect (stressed for time) but for now 2.6.32 seems to work nicely, used it for a day without a disconnect (usually takes 10-20min).
alright.. glad your system doesn't disconnect like it was.
Justin, we have a few set of fixes for power save and ath9k which I'd like to push for the 2.6.32.1 release. These are important fixes and would like to know if they fix your powersave issues *instead* of just disabling powersave completely from ath9k. You can apply the patches from this directory: http://kernel.org/pub/linux/kernel/people/mcgrof/patches/ath9k/2009-12-08/for-2.6.32/ Of these 3 fixes only 2 of them really apply to power save and will help AR9280. The other patch is a fix for AR9285 but just go ahead and apply it as well. Then to re-enable PS by default you can apply this final patch: http://kernel.org/pub/linux/kernel/people/mcgrof/patches/ath9k/2009-12-08/ath9k-ps-enable.patch Or you can also just enable power save manually: iwconfig wlan0 power on Please let me know how this goes.
alright, let me apply the patches and see.

Hm, OK -- this is odd. Lets try a few things. The current logs you provide show nothing to indicate to me what ath9k could be doing wrong so we would need to increase verbosity on mac80211 and/or ath9k to dig deeper into this. I am also curious about the version of wpa_supplicant you are using. Although this should not change matters much I have in few cases now have seen some odd issues cured with an upgrade on it. So a simple test is if you can you try running a newer wpa_supplicant? Then after doing a quick test with that then please use the same kernel / userespace that had the issues and enable: CONFIG_MAC80211_DEBUG_MENU=y CONFIG_MAC80211_VERBOSE_PS_DEBUG=y CONFIG_ATH9K_DEBUG=y First get info just with thew new found PS_DEBUG enabled and paste that. If that doesn't give us enough information we can then try to get down and dirty into ath9k by enabling a driver debug for power save: sudo modprobe ath9k debug=0x00000800 This will enable all prints in the driver with ATH_DBG_PS. If this doesn't give us any clues we can turn to enabling config debug as well, this is 0x00000200. So to enable both you would use: sudo modprobe ath9k debug=0xa00
still seeing disconnects, but with this run(should of tested the other better), seems to fire within 5min of starting up, then another about 5/8 min later, then always around 30min(give or take) of running. Seems the only real bad disconnect was the first, in of when the music crapped out. other than that seems to hold itself, when the disconnects happen.

Thanks for the details. We'll need increased verbose debugging from the ath9k driver. No probe responses are coming back at all so we need to see what the driver sees and does. Oh and far as a version of wpa_supplicant is convered, I was hoping something a little newer like the development snapshot. Seems even ubuntu 9.10 ships something newer, some the 0.6.9 is the latest stable release for example. Maybe even the development 0.7.0 snapshot. This should not matter though, am just curious. The exact issue should hopefeully come out with ath9k debug flags enabled.
ok I'll look at the snapshot later on. right now heres the debug using what you supplied: [ 2543.492286] ath9k 0000:03:00.0: PCI INT A disabled [ 2543.492422] ath9k: Driver unloaded /sbin/modprobe ath9k debud*** [ 2585.113799] ath9k 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 [ 2585.113821] ath9k 0000:03:00.0: setting latency timer to 64 [ 2585.246170] ath: EEPROM regdomain: 0x64 [ 2585.246173] ath: EEPROM indicates we should expect a direct regpair map [ 2585.246177] ath: Country alpha2 being used: 00 [ 2585.246178] ath: Regpair used: 0x64 [ 2585.247443] phy1: Selected rate control algorithm 'ath9k_rate_control' [ 2585.248890] Registered led device: ath9k-phy1::radio [ 2585.248948] Registered led device: ath9k-phy1::assoc [ 2585.249148] Registered led device: ath9k-phy1::tx [ 2585.249212] Registered led device: ath9k-phy1::rx [ 2585.249231] phy1: Atheros AR5418 MAC/BB Rev:2 AR5133 RF Rev:81: mem=0xffffc90000120000, irq=17 [ 2595.949602] phy1: device no longer idle - scanning [ 2598.395214] phy1: device now idle [ 2598.399084] wlan0: deauthenticating from 00:1e:2a:00:67:f0 by local choice (reason=3) [ 2598.399125] phy1: device no longer idle - in use [ 2598.399129] wlan0: direct probe to AP 00:1e:2a:00:67:f0 (try 1) [ 2598.402618] wlan0: direct probe responded [ 2598.402625] wlan0: authenticate with AP 00:1e:2a:00:67:f0 (try 1) [ 2598.409028] wlan0: authenticated [ 2598.409072] wlan0: associate with AP 00:1e:2a:00:67:f0 (try 1) [ 2598.411393] wlan0: RX AssocResp from 00:1e:2a:00:67:f0 (capab=0x431 status=0 aid=1) [ 2598.411400] wlan0: associated [ 2598.411418] phy1: Allocated STA 00:1e:2a:00:67:f0 [ 2598.411433] phy1: Inserted STA 00:1e:2a:00:67:f0 [ 2598.599284] ath9k: Reconfigure Beacon timers based on timestamp from the AP [ 2725.701309] wlan0: detected beacon loss from AP - sending probe request [ 2726.201338] No probe response from AP 00:1e:2a:00:67:f0 after 500ms, try 1 [ 2726.701312] No probe response from AP 00:1e:2a:00:67:f0 after 500ms, try 2 [ 2727.201098] No probe response from AP 00:1e:2a:00:67:f0 after 500ms, try 3 [ 2727.701353] No probe response from AP 00:1e:2a:00:67:f0 after 500ms, try 4 [ 2728.201105] No probe response from AP 00:1e:2a:00:67:f0 after 500ms, disconnecting.

OK -- thanks a lot. Now please run with this enabled as well: CONFIG_MAC80211_VERBOSE_DEBUG I just noticed mac80211 on 2.6.32 drops *all* unacked frames frames when in power save mode, instead of trying to retransmit and if it does we should see a print like: printk(KERN_DEBUG "%s: dropped TX filtered frame, " "queue_len=%d PS=%d @%lu\n", wiphy_name(local->hw.wiphy), skb_queue_len(&sta->tx_filtered), !!test_sta_flags(sta, WLAN_STA_PS), jiffies); I do wonder if the probe request we send out is actually hitting the AP. If the AP disassociated us without us noticing this the AP could technically start ignoring direct probe requests so if this is the case one possible solution would be to probe the AP all the time using the broadcast address instead of sending directed probes. Just my current theory based on your minimal log outputs. When you re-run your tests it'd be appreciated if you can run with ath9k debug enabled as well with config debug now. So: sudo modprobe ath9k debug=0xa00
o.k. CONFIG_MAC80211_VERBOSE_DEBUG=y is set to y in my .config should I have set something in kernel hacking. if not I'll still run your debug for ath9k and post it.

Great thanks, this helps a lot. OK the only issue I see with the printed log is this: [ 326.585734] ath9k: RX filter 0x0 bssid 00:1e:2a:00:67:f0 aid 0x0 But that is updated right after with: [ 326.585749] ath9k: Bss Info ASSOC 1, bssid: 00:1e:2a:00:67:f0 so the old aid value is properly updated but until later during ath9k_bss_assoc_info(). Can't see any other thing which might help here. Lets try increasing the log completely now. Please try with: sudo modprobe ath9k debug=0xffffffff I also noticed this print output is for AR5418 while the original poster of this bug report was for AR9280. Kristoffer Ericson, can you test the patches as well? Do you still experiences the issues just as Justin?
Alright, I'll have a look tomorrow(too tired, need a beer, and need to sit and not think);

And this is the final failure. Unfortunately nothing new is telling is indicative of what may cause the issue. Justin, just to confirm, if you load ath9k (without debugging parameters passed to ath9k), can you verify that this issue does not occur if prior to running wpa_supplicant manually you can first run: iwconfig wlan0 power off I'd also like you to provide the output of this command prior to running wpa_supplicant manually: ps -ef| egrep -i "supplicant|Netwo|nm-app" Which distribution is this on?
o.k. I gather that info for you (apologize for the delay);
Interesting thing here(happened yesterday as well), is on a cold boot recreating the bug takes longer than when the machine is warmed up. normally takes about 5min for the first disconnect, then in between 5-12 min after the 5min mark, then almost always at 30min or so of running. With a cold boot the first disconnect took around 22-25 min. (wondering if this is some cpu thing). Anyways here's the info you wanted: iwconfig wlan0 power off system runs fine(running straight for 40 min without no signs of a disconnect from wpa_supplicant). ps -ef| egrep -i "supplicant|Netwo|nm-app" root 1553 1349 0 21:42 pts/0 00:00:00 /sbin/wpa_supplicant -Dwext -i wlan0 -c /home/name/wire name 1652 1538 0 22:20 pts/5 00:00:00 egrep -i supplicant|Netwo|nm-app and config for wpa_supplicant cat /home/name/wire ap_scan=1 ctrl_interface=/var/run/wpa_supplicant network={ ssid="JPM" #ssid="attwifi" scan_ssid=0 key_mgmt=NONE auth_alg=SHARED wep_key0=xxxxxxxxxxxxxxxxx wep_tx_keyidx=0 priority=5 } (this config is from wicd-client) The system is a clfs system built a few weeks ago. with this build I used these CFLAGS with every app except libflash CFLAGS="-m64 -mtune=core2 -march=core2 -O2 -pipe -fomit-frame-pointer" CXXFLAGS="${CFLAGS}" MAKEOPTS="{-j3}" gcc is = gcc version 4.4.2 any other info you need let me know. I'll build the latest wpa_supplicant just to verify that.
Bug 14664 is a duplicate of this issue. I made some comments there: http://bugzilla.kernel.org/show_bug.cgi?id=14664#c1 With power management off I ran the older kernel fine over night, no disconnect for over 13 hours. I have now merged wireless-testing master into my kernel, latest in drivers/net/wireless/ath is commit e49dd47a04400e3b5c28f661f5674fa130de5357 from Dec 12. This kernel defaults to power management off, per commit 900293de386ba193aed3eab95ddfaa044c9428c4 from Nov 23. I booted, brought the interface up, set SSID using iwconfig (associated), set IP address, brought up a VPN, then ran iwconfig eth1 power on. After a few minutes I got 'No probe response', as with my previous kernel. Disabled power management, brought eth1 down and up, restored route, restarted VPN and I am running fine now. I am using an AR5008 according to lspci, "phy0: Atheros AR5416 MAC/BB Rev:2 AR5133 RF Rev:81: mem=0xf8320000, irq=21" (see bug 14664 for more dmesg output) in STA mode without any wpa_supplicant. My kernel has CONFIG_NO_HZ and CONFIG_HZ=1000. CONFIG_MAC80211_VERBOSE_PS_DEBUG seems irrelevant since my card is not in AP mode, but I will enable all debugging mentioned above and follow up with output shortly.

Peter you're using wireless-testing, that's different, please use linux-wireless to follow up on that and also be sure to include your device (AR5416, AR9280, etc) on your reports to the list.
Justin, any luck with a newer wpa_supplicant? I will note you are using AR5416, one of the older first generation 802.11n hardware devices by Atheros so it is likely your device may have an issue while AR9280 and newer devices will not. The original reporter of this bug report though is Kristoffer Ericson and the device present on the report is AR9280. I haven't heard back from Kristoffer since we advised to test the new patches... Justin, if you follow linux-wireless you will notice that Sujith recently posted some new patches in which he Cc'd stable. Those patches will eventually get merged onto the next 2.6.32.y release -- can you go ahead and just apply them on top of the other patches I asked you to merge. I haven't yet gotten a chance to gather those patches into a URL for users to apply... if someone can do that that would be appreciated. I'd like to see this bug report closed and power save enable by default again on ath9k upstream.

Most likely we are not experiencing the same bug (me and justin). Would you like me to test any patches on 2.6.31 to see if it works? > > Justin, if you follow linux-wireless you will notice that Sujith recently > posted some new patches in which he Cc'd stable.

o.k. a bit late at the moment, but in the morning I'll clean the slate and start fresh. I want to close this as well.
Since I first saw this issue with .32-rc6, and I still do with wireless-testing, I thought it might be relevant to add my information here. I will go away onto mailing lists now, but it does seem like duplicated effort for one and the same issue. Thanks!
Well stable fixes are separate, development issues can be propagated into stable so if you are using wireless-testing due to the delta there it is just no worth trying to figure whether or not your issue pertains to the new code changes or something different. For this bug report please keep the issue to 2.6.32. So far it seems AR5416 remains with issues with ps enabled by default and AR9280 issue is gone.
Created attachment 24227 [details] kernel-config-macbook-AR5008 here is my .config please look over to make sure I didn't forget anything. (there was a similar bug report for wpa_supplicant, that I did, and came to the conclusion that I had missed something in my .config); BTW: the card I have is AR5008
looking at the archives for linux-wireless I'm seeing a bunch of patches. searching Sujith gives me stuff from feb of 09. if anybody can where are these patches that where submitted via CC's so I can test them(the other patches are plugged in with 2.6.32-rc8, but break on current HEAD);
http://marc.info/?l=linux-wireless&r=3&b=200912&w=2 Patchwork has them in git am'able form: http://patchwork.kernel.org/project/linux-wireless/list/
cool thanks.. threw in latest git wpa_supplicant, then I'll throw in these 6 patches on top of the other patches. current HEAD over here is at 2.6.32-rc8
Hmm, are you using Linus' tree or downloading a tarball? 2.6.32.1 is already out, 2.6.32.2 is on its way. Some of the patches mentioned here will be merged on 2.6.31.2 but Sujiths' latest ones won't make it until 2.6.32.3.
using Linus's tree did a git reset --hard origin v2.6.32-rc8. if you need me to pull a branch(wireless, or next) let me know.
Actually jump to hpa's tree now to get 2.6.32.y: git://git.kernel.org/pub/scm/linux/kernel/git/hpa/linux-2.6-allstable.git the master bring will always follow Linus so now that's 2.6.33-rc1, but hpa has branches for the stable 2.6.3x.y releases so do: git checkout -b linux-2.6.32.y origin/linux-2.6.32.y Then check git log on drivers/net/wireless/ath/ath9k/ for the latest patches merged, you can also check mac80211 (dynamic ps fix may or may not be there I forget, I don't think so).
alright.. at the moment plugging in sujith's patches. then I'll go from there.
doing a git reset --hard v2.6.32-rc8 and then applying the first patches in comment #34 works fine, but adding patches 1/6 from sujith error's out for me main.c 1648 error common undeclared(first use in this function I'll look around or to see if I can find the rest of "common" to add to the kernel to test these patches out on top of the patches on comment #34.
Nah don't bother that's a lot of code, those patches need to be backported to be applied to 2.6.32 it seems.
alright.. I'll pull allstable(as I type), and see how the wireless reacts. then go from there
o.k. running linux-stable so far so good, up 7 min's and am not seeing a disconnect, will run her for an hour or two just to make sure. BTW: I noticed powermanagement was off with iwconfig so before starting wpa_supplicant I went iwconfig wlan0 power on (hopefully this is a go);
yeah 2.6.32.2 got a power management got disabled by default. BTW 2.6.32.2 was just released. You may want to: git checkout master git pull git checkout linux-2.6.32.y git rebase origin/linux-2.6.32.y git revert 54ab040d24904d1fa2c0a6a27936b7c56a4efb24. The last command reverts the patch which disable PS by default. Are you using linux-stable git tree using the master branch or the 2.6.32.y branch?

Oh well, OK if that makes your AR5416 happy that's fine too. That's the same thing as Linus' tree when you use the master branch. The purpose of the tree I gave you was to see if you want to debug 2.6.32.y further. For the next 2.6.32.y you would need that tree. Oh and you don't have to kill wpa_supplicant .. you should be fine with using it, in fact I recommend it as disconnections are inevitable, consider the AP detecting your idle for too long and it deassocs you. For a non-encrypted network you can use something like: ctrl_interface=/var/run/wpa_supplicant ap_scan=1 network={ ssid="foobar" scan_ssid=1 key_mgmt=NONE } Another thing you can try is running wpa_supplicant with -D nl80211 instead of -D wext
alright.. well I leave wpa_supplicant as is for now. I'll just wait and see if there's any other patches to test. As for looking at the code I can try, but am not familiar with it(hopefully one day);
might have missed a post.. but this should stay open.
Hello, Having a problem with webcam disconnecting wlan device. Searching keyworld from kernel message lead me to this bug. Does anybody also think it is related to https://bugs.launchpad.net/linux/+bug/647501 ? Thanks
tough to say.. right now running the latest Mainline and everything seems o.k. (no disconnects etc...(although I do see the message in dmesg)from what I remember this was caused by having powersave turned on with the wireless driver. In your case iwconfig wlan* power off can let you know if this is the problem or not. (over here I had radio streaming, plus hulu streaming then after a few mins everything would crap out for a few seconds, then go back to normal(once powersave was disabled everything streamed clean without disconnects)).
With power management disabled, this bug still exists on my AR5008 (DWA-522) hardware. Notably this is currently included in the 2.6.32 source now frozen to ship with the next release of Debian, 6.0-Squeeze, which I have upgraded to. D-Link System Inc DWA-552 802.11n Xtreme N Desktop Adapter (rev A1) ieee80211 phy0: Atheros AR5416 MAC/BB Rev:2 AR2133 RF Rev:81 There is a downstream bug for Debian linked here where I have posted some additional details: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=556009 I am currently testing the 2010-10-20 compat-wireless against the Debian 2.6.32 kernel to see if this is actually resolved in the latest version with the hope that it works and a patch for 2.6.32 can be created somehow for ath9k, as I suspect that merging current compat-wireless is a show-stopper for the now-frozen Debian kernel.
Upgrade: http://wireless.kernel.org/en/users/Download/stable/
Thank Luis. I am already running the latest. If this tests okay, I'll try the June 2.6.32.16 compat-wireless linked above in hopes the narrower patchset might be close to what is in the current 2.6.32.24 kernel used by Debian. I expect the newer ath9k I am using will work fine for *me*; I am happy about that. It is patching of the distribution kernel packages that I am trying to facilitate to enable an easily sustainable process to maintain the driver without risk to future kernel upgrades for enterprise use on Debian. The simple/ideal solution would be to hand feed a small patchset to the Debian package maintainer. Unfortunately it appears that the root cause/commit of this issue or a solution is not easily identifiable per Justin's attempts. (https://bugzilla.kernel.org/show_bug.cgi?id=14267#c71) I might assume it is less work to avoid AR5416+AR2133 than invest time in creating a suitable patch for the Debian kernel, noting this is probably the oldest non-legacy ath9k radio combination supported.
There are a few stable patches pending integration into 2.6.32 even for Power Save. The only way for a patch to make it into 2.6.32 is first to add it to Linus' tree. If you are not familiar with this process, please read: http://wireless.kernel.org/en/users/Documentation/Fix_Propagation We have already tagged a lot of patches for stable consideration, it takes a while to propagate. But we cannot propagate features or new code. For that you'll need a newer kernel. I used to recommend at least 2.6.32 for ath9k, today that has switched to 2.6.36, and if you're stuck on 2.6.32, you can use compat-wireless-2.6.36, which is why we created it. What debian can do is make a compat-wireless package for users wishing to upgrade their 802.11 and BT subystem to 2.6.36, its what Ubuntu does with their linux-backports-modules package.
Well.. after upgrading to the latest 2010-10-20 compat-wireless, I am still seeing ath9k disconnect from my AP. Oct 21 20:28:10 maple kernel: [183437.317018] ieee80211 phy0: ath1: No probe response from AP 00:01:46:XX:XX:XX after 500ms, disconnecting. Oct 21 22:39:12 maple kernel: [ 539.316041] ieee80211 phy0: ath1: No probe response from AP 00:01:46:XX:XX:XX after 500ms, disconnecting. maple:~# modinfo ath9k filename: /lib/modules/2.6.32-5-xen-amd64/updates/drivers/net/wireless/ath/ath9k/ath9k.ko
so the disabling of the powersave made no difference..over here disabling gave me a clean run of things.. I just loaded the latest Mainline and will have a look if the disconnect is happening as well over here.(will bisect again just to see when I have time, are you able to bisect? since the powersave option made no difference for you(maybe it's another commit)).
In my case, I don't have a working starting point, having moved directly into this bug from an older working madwifi+AR5001 hardware setup. I am going test out the published stable versions (linked above) between vanilla 2.6.32 and bleeding edge to see if I can find a working patch set. I am going to try and setup another ath9k that does not have this issue at the same location to more effectively rule out any uniqueness at the AP.
I believe this issue is still there, but Atheros does not support this chipset and I am fairly sure that only they have access to the information that is needed to really fix this problem. My guess is that RX just stops working at some point, causing the disassociation. I have absolutely given up on using AR5416 as STA because of the lack of support and interest from Atheros. I'd suggest not wasting time on it. However, AR5416 works well as AP, so the card isn't completely useless.
I just finished testing against stable compat-wireless 2.6.32.16, 2.6.33.6, 2.6.34.1, 2.6.35-1 and 2.6.36-rc5-2-s in addition to the bleeding 2010-10-20. In every case I have this issue. Using 2.6.35-1 I was able to watch a 1GB movie over wireless with only one interruption, so I am sticking with that for further testing, though today its down frequently. I might note 2.6.36-rc5 had speed issues for me in two separate tests over a reboot, but it is *rc* so that might be expected. My other ath9k (928X) is fine, as are all other devices and smartphones. My AP is a DI-624M(v2.5). Its an AR5513 under the hood, and I have it set to pure 11g-only, 64bit WEP. Its defaults are Beacon 100ms, RTS 2313 B, Frag 2346 B, DTIM Interval 4, CTS Auto, Long Preamble with TX Rate auto, and power 100%/17dBM. I picked this hardware because it appears to be an affordable and common PCI radio combo that supports ath9k.. and solve my many(5?) years workaround waiting to re-bridge my media VMs with wifi which I have not been able to do since pre_ng_madwifi with my AR5212 (DWL-G520 PCI) which this AR5416 replaced six months ago. I did not experience a regression (never ran 2.6.31), as I saw similar issues running this device on ath5k on 2.6.26 (Debian 5.0) over the last six months, but it was far less frequent, to the point where I'd just run a quick ssh script from my phone to re-associate in seconds when it occurred.
s/ath5k/ath_pci/g on my #91 comment regarding the AR5416 on Debian 5.0 so the bug exists with this hardware and older madwifi 0.9.4+r3772.20080716-1. Also s/AR5001/AR5212/g on my #89 comment (too many atheros chipsets around here). I switched back to my old AR5212, and it is working OK so far with current compat-wireless ath5k on Debian 6.0 (ANI support for ath5k was not available previously), and I think I may be able to bridge it in STA mode too with a recent iw patch I just applied to my deb-src: http://www.spinics.net/lists/linux-wireless/msg56681.html. I'll stick my AR5416 into a wired Ubuntu desktop where it will receive the packaged compat-wireless updates so I can periodically test and provide feedback when I see updates here. I'd like to get back to better performance of the ath9k even on my 11g network.
Is this still an issue on >2.6.38-rc7 ?
Hey florian, I doubt it. Im currently using linux-next from first of march and its working well. Looks like thats equal to v2.6.38-rc6 so unless something big happend in -rc7 it should be fine, atleast on my end.
right now I am using the Mainline kernel and am seeing nothing like before. movie plays on hulu without stuttering/stopping after 15mins or so. will continue to watch and report anything.
Ok, cool. I'm closing this as unreproducible then. Or... you don't happen to know which commit fixed it?
