    The build time (of version 2.2.17) was 300 seconds +/- 20 seconds
    with Linux version 2.2.17.

    The build time (of version 2.2.17) is now 1240 seconds +/- 20 seconds
    with Linux version 2.4.0.

    So the system is about 4 times slower.

    Also, I get some CPU watchdog timeout that I didn't ask for Grrr...

    The NMI and LOC (timers) run faster than timer channel 0. This
    cannot be correct. Anybody know what this is and how to get
    rid of these CPU time stealers?
