I have a Lenovo X61s with F12, kernel 2.6.32.11-99.fc12.i686.PAE
I normally use Network Manager to manage the wireless, however, recently my events/0 process is using 50% CPU time (measured with top -d 60).
The load stays high even if I disable the wireless and remove the iwlagn module. The machine doesn't have a wired connection.
"/etc/init.d/NetworkManager stop" cures the problem and brings the load down.
When NetworkManager is running, but with disabled wireless, I don't see anything special in /proc/interrupts, except for the timers.
Why is Network Manager generating all these events? How do I stop it from doing this - keeping Network Manager running?

Booting kernels 2.6.32.10-90.fc12.i686.PAE or 2.6.32.9-70.fc12.i686.PAE show same behavior.
When the CPU load is high, the machine is slow to respond to keyboard events.

I've found the solution:
The e1000e NIC had stopped working, which I hadn't noticed since I'm nearly always on wireless.
Shutting down and starting again didn't solve the problem.
I had to remove the battery from the laptop and inserting it again after a few minutes to get the NIC to reset.
No more high CPU load from events/[01].
