 Hmm, I could not reproduce this failure on my DS10.
 
 My environment is
 
 - kernel around Aug 9
 - userland around Aug 3 + patched libc
 
 And
 
 ds10$ sysctl -a | grep unaligned
 machdep.unaligned_print = 1
 machdep.unaligned_fix = 1
 machdep.unaligned_sigbus = 0
 
 (Nothing added to /etc/sysctl.conf)
 
 ds10$ tar --version
 bsdtar 3.4.0 - libarchive 3.4.0 zlib/1.2.10 liblzma/5.2.4 bz2lib/1.0.8
 
 I will lose access to my DS10 for next few days. After that,
 I will try new kernel and userland.
 
 Thanks,
 rin
