It is already queued for 2.6.33 and should be in next stable release. See http://git.kernel.org/?p=linux/kernel/git/stable/stable-queue.git;a=blob;f=queue-2.6.33/iwlwifi-use-dma_alloc_coherent.patch;h=1e90f1a5503d428bcbbd17fab5d415a8b3ac295b;hb=c2cde1eaaa4733154b664f1a0f0905fadcb4cb06
indeed fixed with iwlwifi-use-dma_alloc_coherent.patch in 2.6.32.11 will open new separate bug if allocations would still fail. It don't seem to be so easily triggable now. thank you
