--- Comment #34 from Waldemar Brodkorb <wbx at openadk dot org> --- Hi, with this patch I still get following output on my Numato Mimas A7 Mini: [ 3.503255] Run /init as init process [ 3.506819] with arguments: [ 3.509763] /init [ 3.512005] with environment: [ 3.515114] HOME=/ [ 3.517706] TERM=linux [ 3.530417] Illegal opcode exception in kernel mode.

An older Linux kernel built with Buildroot 2018.11 does boot fine, so I do not think it is my bitstream, which is behaving wrong. What could be the reason for this panic?
