I've noticed a strange behavior w/r/t the high CPU load.

With wifi enabled, ksoftirqd will use 100% CPU even if I am not
connected to a network. However, if I create an ad-hoc network,
ksoftirqd will stop. Disconnect the ad-hoc network and it stays that
way, no CPU load, UNTIL connecting to a wifi network again. Then the CPU
load will again reach 100%.

Here's hoping that this will help somebody get to the bottom of the
problem.
