We are building a suse arm on our arm-a15 board, Linux kernel is linaro 3.12.0 version, and compiler is arm-linux-gnueabihf-,
For reference, is it about this HiSilicon board? https://wiki.linaro.org/Boards/D01
we got suse source and mount it on by nfsserver.
when I chroot to suse, a error occured like this: sh (81): undefined instruction: pc=b6f76b48

Have you tried running any test program with NEON instructions? According to http://en.wikipedia.org/wiki/Comparison_of_ARMv7-A_cores that is non-optional on Cortex-A15, and my Chromebook with working Factory has it in /proc/cpuinfo. Our armv7hl compiler does not require NEON, but glibc may make assumptions that don't apply to your hardware. My colleagues will have more details on what their debugging indicated.
