After update to pulseaudio-1.1-8.fc17.x86_64 this bug may be closed.
glibc vas update to 2.15-28.fc17.x86_64 too.
the bug is still there, the kernel just had debug turned off by default now. (The kernel-debug flavour will still show this warning).
My mistake this bug appear on dmesg.
If you run the 3.4.x kernel-debug kernel, do you still see this?
