Hi all, I cannot load a x86_64 kernel with kexec on 2.6.31; the error message is:
Can't find kernel text map area from kcore Cannot load /boot/vmlinuz Digging through the source I found a mismatch between the assumed kernel text size; kexec has: #define KERNEL_TEXT_SIZE (40UL*1024*1024) but on the kernel side we have: include/asm/page_64_types.h: #define KERNEL_IMAGE_SIZE (512 * 1024 * 1024) And, indeed, changing the definition in kexec-tools to the kernel one fixed the problem. Not sure if this has been reported before, if so please ignore the noise.
