Thomas,
Can you apply this patch (with the fixed "tested-by") and push out a new 3.2-rt?
This bug is causing one of my "stable tests" to fail, and I wont push out a new stable test until it passes. But I also wont add a fix that is not in your tree. This means that 3.0-rt is being held back until this gets applied.
Thanks,
-- Steve
