Unable to handle kernel paging request at virtual address f600030a

Today, when porting the Linux operating system, download the compiled Linux kernel to the Development Board with inexplicable hints (my development Board is a CS8900A driver):

Unable to handle kernel paging request at virtual address f600030a

After analysis, the original Linux kernel cs89x0 drive has a problem, so the previous Development Board of the cs89x0 drive copy to overwrite it, in the compilation, OK, through, but the new problem arises again, because the following this problem tangled I almost a day, So I'll describe the solution in detail in the next blog.
