[bf1942] Cpu usage when empty!

Common issue with Linux kernels. Seems to be less prominent on some
kernel configs. I had the same when testing on 2.4.X in the end I created
a config which didn't have the issue but I couldn't find the common option
due to the randomness of the Linux config generator :(
FreeBSD also doesn't suffer from this.
