These failures are present in the AArch64 little endian as well. After giving a closer look at the issue, it doesn't look at a kernel issue, but at how ptrace is invoked the gather registers: it uses PTRACE_PEEKUSER whereas it not supported on AArch64 where the PTRACE_GETREGSET ptrace request should be used. I'm testing a patch for that, it doesn't work so far, but we can now access the registers and then an error occurs because no unwind information are found when we're in _start.
