This patch works great for me. It did not apply cleanly to the latest GIT pull from the Linus' tree: # patch -p1 < ~/Downloads/tid.patch patching file drivers/net/wireless/iwlwifi/iwl-agn-tx.c patching file drivers/net/wireless/iwlwifi/iwl-trans-pcie.c Hunk #1 succeeded at 1261 (offset -290 lines).
