I have the same thing on my Asus P5WDG WS PRO board. Like you it has Intel sound, and the Intel sound device is one of the "stuck" modprobe processes.

In my case I get 2-3 modprobe processes stuck with a 'D' state (waiting on I/O). This causes my system load average to sit at 2.0 or higher.

I can leave them for a very long time and they do not appear to go away.

From the dmesg output I suspect we have the same or similar chipsets in our mainboards. I do not have this issue with the Precise kernel (3.2.0-x), but it is definitely there with 3.5.0-19 and 3.5.0-21
