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 -0800iwlwifi: 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:

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.

same here... Intel Wifi Link 5300

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

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

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

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

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

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?

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.

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

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

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