Hi, I'm really sorry because I did not have time to work again on the patch, which I confirm is working for the application we developed it for. There were surely a couple of problems that made it difficult to be for general use: the first (probably simple to solve) is about physical/virtual mapping, Simon suggestion was about removing #ifdef __MIPSEL__ stuff in kexec.c the second, a bit harder (for me at least), is that I had to insert cache flushing code in kexec tools assembly part because leaving the job to the kernel did not work I don't know if I will have time for it in the near future because it implies quite a bit of studying for me... anyway I'll keep an eye on it but I cannot promise bye Francesco
