The issue is gone if I use a fresh fs:

pc12909!root:/mnt # touch foo
pc12909!root:/mnt # ls -al
total 2
drwxr-xr-x   1 root  wheel     0B Apr 10 09:08 ./
drwxr-xr-x  18 root  wheel   512B Apr  9 17:39 ../
-rw-r--r--   1 root  wheel     0B Apr 10 09:10 foo

If I copy the tarball to the newly created fs above, the ls problem is
back:

pc12909!root:/mnt # cp /root/ports.tar.gz .
pc12909!root:/mnt # ls -al
total 0

The tarball is a standard FreeBSD ports.tar.gz.  Extracting fails:

pc12909!root:/mnt # tar xfz ports.tar.gz
ports/audio/juk/pkg-plist: Error reading 'ports.tar.gz'gzip
decompression failed
tar: Error exit delayed from previous errors.

A final "ls" broke the machine.  No clue if its related to hammer,
because I have no physical access to the machine ATM.  Will look
at the crash later and post logs/dump if available.
