[SOLVED]iwlagn problem after kernel update

devil_kc · 2010-03-17 09:03:51

yesterday i updated kernel to 2.6.32.10. after reboot kernel.log started with messages like:
Mar 17 09:59:43 laptop kernel: iwlagn 0000:04:00.0: free more than tfds_in_queue (0:1)
log creates that message when i do something online. looks like every time i reload page/ping/do anything online that message goes to kernel.log.

the thing that
worries me is this:

% cat /var/log/kernel.log | grep tfds_in_que | wc -l
20106

my computer is up for less than an hour.
wlan card is intel 5100
does anyone have any suggestion? go back to kernel 2..6.32.9?

EDIT: everything else works fine. wlan is working without a problem.

i confirm that have the same problem
Network controller: Intel Corporation Wireless WiFi Link 5100

[root@hermes ~]# cat /var/log/kernel.log|grep tfds_in_queue|wc -l
40871
[root@hermes ~]# uptime
 20:52:08 up  1:18,  2 users,  load average: 0.00, 0.02, 0.05

this is really nasty

from changelog on kernel.org i find this:

commit 44af042e42f2231579ea8ef7586d3789d198f609
Author: Stanislaw Gruszka <sgruszka@redhat.com>
Date: Fri Feb 19 15:47:33 2010 -0800
iwlwifi: sanity check before counting number of tfds can be free

commit a120e912eb51e347f36c71b60a1d13af74d30e83 upstream.

Check the frame control for ieee80211_is_data_qos() is true before
counting the number of tfds can be free, the tfds_in_queue only
increment when ieee80211_is_data_qos() is true before transmit; so it
should only decrement if the type match.

Remove ieee80211_is_data_qos check for frame_ctrl in tx_resp to avoid
invalid information pass from uCode.

kernel 2.6.32.10 needs this patch I think:
http://www.spinics.net/lists/linux-wire … 47806.html

kendyjm · 2010-03-17 12:42:50

same here with an Intel Wireless WiFi 4965AGN.
Kernel 2.6.32.9-1 works fine.

Thanks for the tip!
Kernel 2.6.32.10 and iwlwifi-4965-ucode caused also problems here.
Switching to Kernel 2.6.32.9-1 solved the problem.

takedown · 2010-03-17 18:55:19

same here... Intel Wifi Link 5300

root:/etc # cat /var/log/kernel.log|grep tfds_in_queue|wc -l
172152

here a bug report: http://bugzilla.intellinuxwireless.org/ … gi?id=2174

Intel Corporation Wireless WiFi Link 5100 here, and yes, my logs are also filling up like a maniac.

$ sudo grep 23:11:40 /var/log/everything.log | grep tfds_in_queue | wc -l
63

63 lines in everything.log per second.

So I sent in a bug report: http://bugs.archlinux.org/task/18735

MiCap · 2010-03-18 18:02:19

Hi! I believe I'm having the same problem with an Intel WiFi Link 4965, but in my case I cannot have a connection.
I do have a connection but when I try to make some connection to outside (ping my own router or other site or trying to use the internet) the connection only lasts about 5 seconds. Then the connection goes down. The networkmanager or wicd or ifconfig says everythinf is ok. To have more 5 seconds of connection I need to connect again to my router.
Any clues? At the moment I'm on windows (boring!), but if you need some log, just ask.
I didn't tried to downgrade the kernel yet, but I'm almost sure that is a kernel problem.
Thanks

Daenyth · 2010-03-18 18:25:40

Has anyone made a bug about this yet? http://bugs.archlinux.org
Might be good to check upstream tracker too.

takedown · 2010-03-18 20:40:45

look two post up you

Daenyth · 2010-03-18 20:48:33

Fail

Kirurgs · 2010-03-19 21:11:31

Hi!

Patch posted by grzech0 is not the most correct one. Later in the discussions they posted the correct patch, which is here http://www.spinics.net/lists/linux-wire … 47998.html
I applied that to my custom kernel and no errors appear afterward. Before that I had like:
cat /var/log/kernel.log | grep tfds_in_que | wc -l
707257
A lot

regards
Kirurgs

maleadt · 2010-03-20 10:12:50

+1 on this issue, going a kernel version back solves it indeed

eleon216 · 2010-03-20 16:45:40

same problem here with 4965AGN
Kernel 2.6.32.9-1 works and 2.6.33.1-1 from testing works too

I have the same problem as MiCap (quoted above). I also have an Intel wireless card, and after upgrading to kernel 2.6.32.10, internet would work for a few seconds and then stop. Downgrading to kernel 2.6.32.9-1 fixed the problem.

But, I don't have the same problem as everyone else. That is, I don't have any entries of "tfds_in_que" in /var/log/kernel.log. Weird.

Today I decided to remove the syslog-ng daemon while waiting to see a new kernel version that fixes this bug, because my log files are growing too much

Isn't that overkill? Just a few log files are affected by this and syslog-ng handles a lot of logs. What's wrong with reverting the kernel?

takedown · 2010-03-29 22:22:04

can be a bit exaggerated, but the system itself performs very well for months, and as a laptop, it bothers me that syslog write 300 lines per minute in different file all the time.
Currently prioritized it, to have a log of events.

kendyjm · 2010-04-09 18:46:50

fyi, core/kernel26 2.6.33.2-1 works fine.
you can close this thread.

dcc24 · 2010-04-09 19:14:56

Confirmed. Fixed in 2.6.33. Please mark the thread as [SOLVED].

takedown · 2010-04-09 19:20:09

yes... confirmed... I think this confirms (joke):

root:/home/takedown # diff /etc/rc.conf /etc/rc.conf.old
87c87
< DAEMONS=(syslog-ng hal @cpufreq @alsa @laptop-mode net-auto-wireless)

confirmed. works fine now.

venky80 · 2010-04-11 17:55:13

I am not able to connect to wireless with my intel 5100 AGN after 2.6.33-2 update

dcc24 · 2010-04-11 17:58:43

This is a different problem, please open a new thread. Still, I have the same card and I can connect just fine.

could you post your lsmod | grep iwl?
