    Markus,

    Ok, I finally got everything working. The interrupt issue was due to a
    bug in the perfmon code.

    But I found another bug in ds.c.

    The absolute maximum MUST be at buffer+size+1 but the threshold can be anywhere
    between the start of the buffer and buffer+size. You had it set past
    the end of the buffer (at +1),
    therefore PEBS was not generating any interrupts.
