Description:
After upgrading on March 17, my kernel.log is filled with one and the same error repeated over and over again:

Mar 26 02:57:22 mylaptop kernel: iwlagn 0000:03:00.0: free more than tfds_in_queue (0:1)

This error is repeated about 35 times a second (!!!) and my computer is getting clogged! Please, help!

I'm not sure what was upgraded at that date. I caught the error just now, so I didn't pay attention then.

I saw that it is reported as a kernel bug on the ubuntu forums.

This happens on my thinkpad t400 laptop.

Additional info:
* package version(s)
* config and/or log files etc.


Steps to reproduce:
Check the log files on an upgraded system (possibly only thinkpad t400 affected?) with a loaded iwlagn.
This task depends upon

Reason for closing:  Fixed
Additional comments about closing:  Fixed in 2.6.33.2 and 2.6.32.11 upstream. At least one of these kernels made it to core.

what kernel version?
Comment by smradlev (smradlev) - Friday, 26 March 2010, 12:40 GMT
kernel26 2.6.32.10-1
Comment by Tomáš Hykel (cloq) - Saturday, 27 March 2010, 17:21 GMT
Same here.

x86_64 2.6.32.10-1 kernel / ThinkPad T500 / Intel PRO/Wireless 5100 AGN / iwlwifi-5000-ucode 8.24.2.12-2.

Reports like "iwlagn 0000:03:00.0: free more than tfds_in_queue (1:2)" are making unbelievable mess in dmesg, each second there are ~2 new ones. Occurs when connected to a WPA2-AES secured Wi-Fi network.

better start submit this upstream as we can't do much about it. also you might want to check kernel 2.6.33.1 from testing to see if does have the same problem.

Has this been submitted upstream yet? I'm affected by this also.

Issue happened on my machine too. I found attached patch on the linux wireless ML (https://patchwork.kernel.org/patch/86722/)

Seems to be solved here for now.

Seems to be solved here as well after kernel upgrade to 2.6.33.
