    Sorry to disturb all of you again, but the thing is still not fixed (or
    better: broken again) for me:

    I saw some patches referring to this problem and was able to compile a
    working kernel somewhen in September (don't know the exact date
    unfortunatley, but the kernel is from 22nd of September, so this is the
    latest possible date). After that I thought the issue had settled.

    However, yesterday I upgraded the system to a recent 7-stable codebase,
    and now it locks again hard after probing the CPU cores. My setup remained
    exactly the same, the new code just does not work.
    Please let me know what I have do to provide further information.

    This is of great concern if in fact that's true.

    I'm adding Jeff Roberson, author of the ULE/SMP2.0 code, to the CC.
