2009/11/17 ??? <06120216 at bjtu.edu.cn>: > i modified both kexec-tools and module in kernel to ingnore some validity checking. but when the code in kernel is going to copy the new kernel to old kernel, a pagefault exception is receive like this: > ~ # kexec -e > Starting new kernel > Unhandled kernel unaligned access[#1]: Maybe it was because of your crosstools problem. watch the 'REG_L s5, (s2) REG_S s5, (s4)' in relocate_kernel.S to see if it is suitable for 64 bits. BTW, if you are using smp processors , you should check the patch for it
