The complete fix is actually not that trivial. It took me a couple of
commits to get this right. The changes from lt 1.5 to 2.2 are far from
trivial. Check git if you want to know more.

Yes, the adoption of PA in Ubuntu didn't work out that well.
One of the biggest problems they have is that they wholeheartedly
adopted closed source drivers (nvidia, ndis, ...) and other
low-quality out-of-kernel drivers which as side effect tend to block
the CPU too often and for too long time which has a negative impact on
the scheduling latencies for programs that rely on reliable scheduling
such as PA.
But hmm, this is not the right place to discuss this and the Ubuntu
guys already know my criticism.
