I don't immediately see anything wrong in your configuration. Which kernel are you using? Your Buildroot configuration builds a toolchain with kernel headers 4.0, are you using a kernel version >= 4.0 ? Could you run sshd under gdb and see which instruction is considered to be invalid? This would be the most helpful way to debug the problem. Thanks, Thomas -- Thomas Petazzoni, CTO, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com
