    I am posting this question here since I tried at comp.unix.solaris
    without having a full picture of the problem with "early" ULTRA III

    1. Can anyone explain when/if the "prefetch" bug is fixed, was that on
    the Copper CPU's or fixed earlier.

    2. Also, on a Blade 1000/2000, what versions shall one try to "avoid"
    due to bugs or other issues with montherboard and CPU combinations?

  2. The bug exists only on the aluminium CPUs with 750Mhz.
    Recent kernel patches detect this and then turn off some pipeline,
    so the CPU is slower but never faulty.
