Hi, In 1a7123cdd9f49cf1c908fb2c16d26f279c88d8c9, John Linville disabled ASPM for iwlwifi: /* W/A - seems to solve weird behavior. We need to remove this if we * don't want to stay in L1 all the time. This wastes a lot of power */ pci_disable_link_state(pdev, PCIE_LINK_STATE_L0S | PCIE_LINK_STATE_L1 | PCIE_LINK_STATE_CLKPM); Now, I took a laptop with 3.7.9 (that supports L1) and measured power. I would expect to see that as long as the driver isn't loaded, the power consumption is low (L1 enabled), and when I load the driver, the power consumption rises because L1 gets disabled. But this is not what I see. I see more the less the same numbers before and after driver load. I don't remember exactly the numbers, but I do remember they were low (around 1mA or so) - but I really need to check. I also removed the code above, and it didn't change anything. Can it be that this code doesn't have any effect? And as you can see, I am not an expert at this...
