Comment 27 for bug 972821

Those new kernels broke my Open Sound System (OSSv4 4.2-2006) installation and VirtualBox. I had to make a chroot environment to build working modules. I'm writing those because both 3.0.0-18 and 3.0.0-19 are responsible for building bad kernel modules.

$ lsmod

You can see that some kernel modules are builded as [permanent] which is not the way it should be (that's with oss modules copied from chroot).

I've struggled to get my sound back for two or three days and I've found solution on VirtualBox bugzilla: https://www.virtualbox.org/ticket/9891#comment:12
