Red Hat Bugzilla – Bug 352791
iwl3945 causes unnecessary wakeups
Last modified: 2009-01-06 18:53:30 EST
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):
Steps to Reproduce:
1. load iwl3945
2. disable network
3. start powertop
interrupts are generated
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.
Changing version to '9' as part of upcoming Fedora 9 GA.

I don't find this to be a problem with 188.8.131.52-117.fc10.i686...
