I was having trouble with my system failing to read disk formats, USB flashdrives, and finally CDROMs, so I built a fresh Kernel from scratch, getting the source from Kernel.Org and running menuconfig. But afterwards, my Nvidia GeForce 9400 GT video drivers would not work. When I posted on Nvidia, they said that there is no support for creating a Kernel Video Driver Module on a 64bit kernel (AMD Athelon 64) running a 32bit user space. Now I am stuck with not knowing how to replace the 64 bit kernel with a new 32 bit Kernel. When I try booting into any of the older Kernels, it eventually fails, fails to establish X windows, or runs into a Kernel Panic, so going backwards does not seem to be an option. But when I reload a new Kernel and compile it, it just comes out 64 bit again. And I can not find anyway using the Ubuntu get software or Update procedure to get a standard Kernel. They only seem to offer something strange called Batman or dbd8d or a RAID kernel.<br>

<br><br>   There must be some fairly straight forward to get Kernel and user space back in sync, I just don&#39;t seem to be able to figure it out. Any suggestions?<br><br>Mike<br>
