I think you must be much more specific. To begin with, which was the last working 2.6 kernel, and which 3.x kernel did you try? I am not a kernel guru, but I know that many core packages depends on the kernel headers. That imply that, in order to insure a good system consistency, you must install the kernel headers with every kernel upgrade, and recompile all the packages that depend on them. Using the packages from a distribution will do those updates for you, but if you are upgrading the kernel yourself, you are on your own with this kernel headers problematic. If you don't make those updates, or make them in a non correct order, anything inclusive the most strange and hard to solve bugs can append, and bigger the steps between the kernels, more problems can, and will, arise. Also, you should run this script http://www.alsa-project.org/alsa-info.sh and when prompted, upload the information and share the link with us. And last but not least: don't use a rt-kernel during compiling - gcc can crash, or worst, it can produce wrong code with them, that even in case of successful compilation. Use a vanilla or the recommended kernel from your distribution when compiling.
