To avoid the config issue, I'd suggest issuing the command 'make oldconfig' in /usr/src/linux instead of copying the /boot/config file. This clones the RUNNING kernel's config. Also, you will likely need to issue 'make modules-install' as opposed to just copying the snd-hda-intel.ko module, since you are building a different version than the pre-built- the modules will be incompatible with your old kernel and modules, so you will need to copy them all, and likely also do a make and make bzImage... ending by booting the kernel you've just built. I'm not familiar with the processes for Ubuntu, as I use SuSE. If you can get sources for the currently running kernel (with the exact same patches etc) as opposed to just generic ones for 2.6.24, you should be able to use these and there will be no need to completely compile the kernel or reinstall ALL modules. Since SuSE provides kernel sources patched EXACTLY to the running kernel, I have no experience with the above, and YMMV. Bjorn.
