Comment 2 Stanislaw Gruszka 2012-01-21 16:11:16 UTC

It is fixed upstream 3.3-rc1 by:

commit b2ccccdca46273c7b321ecf5041c362cd950da20
Author: Wey-Yi Guy <wey-yi.w.guy@intel.com>
Date:   Thu Nov 10 06:55:04 2011 -0800

    iwlagn: check for SMPS mode
    
    Check and report WARN only when its invalid

We need backport that to -stable

Comment 3 Stanislaw Gruszka 2012-01-23 15:27:55 UTC

I posted patches for currently maintained -stable releases (3.0 and 3.2)
http://article.gmane.org/gmane.linux.kernel.wireless.general/84253
http://article.gmane.org/gmane.linux.kernel.wireless.general/84251

Since fix is committed in upstream kernel, I'm closing the bug with CODE_FIX status.
