No idea where this comes from beyond "init crashed", but that first number (ffffffffffffffe0) is (unsigned)(-32). > Though I tested same initramfs with kernel 3.18, and it worked. > > Is there any option to select the kernel version in busybox setting or > should I pick up older version busybox. You may have an issue with your build environment, rather than busybox. I presume that "default gcc compiler" means "whatever gcc/binutils/glibc version my distro ships with". Searching for Linux 3.16.7-29 seems to point to OpenSUSE 13.2, which uses GCC 4.8 and glibc 2.19 by default. There can be some issues with building a glibc binary to run on an old kernel while using a version of glibc built on a new kernel, with new kernel headers. Knowing nothing more than what you said, I'd suspect that this is the issue. If you're wondering what that means in practical terms: I suspect you need a different toolchain, such as a chroot with an older environment.
