Johannes, this is on a 2.6.38.8 (more-or-less) kernel -- not sure if this is a problem that still exists upstream, but I didn't easily find any patches in wireless-testing that obviously related to this.  Any ideas?

Comment 4 John W. Linville 2011-08-24 15:42:42 UTC

Does this problem persist with 2.6.40 (or later) kernels?
