lucid iwlagn free more than tfds_in_queue

Bug Description

on lucid beta 1 my connection drops completely for approx a minute or degrades to 1 mbit/s

this may be related to http://bugs.archlinux.org/task/18735 and/or http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=574526 which seem to make wpa2 responsible for the problem...

kern.log is flooded with "free more than tfds_in_queue" messages

Confirmed, it has DOS proportions here. My kern.log is already at 700MB and rsyslog is taking nearly one core at full CPU.

Same for me. Happened after update from 2.6.32-16 to 2.6.32-17.

I guess this patch should fix it
https://patchwork.kernel.org/patch/86722/

I am preparing a test kernel for the message issue. This probably does not fix any continuous drops and reconnects. Those I would continue on https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/544254 to keep things separated.

Ok, test kernels have been uploaded to http://people.canonical.com/~smb/lp545585/ Please test and give feedback here. Thanks you.

Works for me! Messages are gone.

works here, too!

Works for me =]

Me too! Only real issue I have had so far ;)

This bug was fixed in the package linux - 2.6.32-18.27
