Strange behaviour

[Felix Oxley]

Hi Magnus, thanks for your reply.

The behaviour of my machine has changed since yesterday!  :-(
I now get this high wake up load without starting FireFox.
Immediatley after boot the machine will show <150 wakeups per second.
Then it will start to show much more.

My problem is that the output of powertop is not giving me any information
about where these wakeups are coming from.
The output of powertop -d is below.
Can any one tell me which process is causing 5000 wakeups?
