I'm sorry, i forgot to report here that "_panic: allocating allocated segment_" is the same bug happening on non-debug builds. I only have a debug build of Illumos, but the troubleshooting was originally done to fix https://github.com/zfsonlinux/zfs/issues/6315 which is a non-debug ZFSonLinux build.
