Stanislaw, do you understand how this is going wrong?  Do you have a
fix?

Hi Ben,

there is patch pending in wireless-2.6 master GIT branch [1]:

commit c8406ea8fa1adde8dc5400127281d497bbcdb84a
"iwlwifi: Silence tfds_in_queue message"

Also, it would be fine to see "[2.6.32] iwlwifi: fix nfreed--" in
debian's 2.6.32 kernel.

Kind Regards,
- Sedat -
