Thank you, regarding to
http://lists.linuxaudio.org/pipermail/linux-audio-tuning/2012-May/000147.html
you've got similar issues.

Since there are other issues on my AV Linux (Debian stable) install
using a 3.0, I'll use a 2.6 kernel, when I drop 3.2.0-23-lowlatency for
Precise. OTOH for a while some 3.0 or 3.x was ok on Arch, but now it's
broken too.

Anyway, perhaps somebody has got an idea:

I guess that later today I'll restore the nvidia's xorg.conf and build a
non-rt preempt 3.0 and/or 2.6 with threadirqs.
Perhaps I'll keep the current kernel after installing a new kernel and
will subscribe to the tuning list.

On Debian list somebody has many issues with latest kernel, while he or
she hasn't with 2.6. I guess non-audio usage.

Ralf
