Description of problem: iwl3945 generates about ~15 wakeups per second, even when network is down. It's more than 10, so powertop reports it in bold 13,7% ( 10,8) <interrupt> : iwl3945 Version-Release number of selected component (if applicable): 2.6.23.1-26.fc8 How reproducible: always Steps to Reproduce: 1. load iwl3945 2. disable network 3. start powertop Actual results: interrupts are generated Expected results: preserving more attery power
What do you see as the standard to meet here?
I think that disabling network with NetworkManager should take iwl3945 down from the top of the list, similarly as using the kill switch does. Intel chose 10 wakeups per second as a threshold, so I believe we should stick to that. Note that I am no expert and have no idea how many wakeups per second are required for the hardware to work properly.
