Command works on all other systems, including Solaris x86, Linux, and a
3.5-STABLE running a non-SMP kernel. User reports that he can not get
directory listing via FTP, or od the directory.
Can not ^C or ^Z in tcsh or zsh, can not kill or kill -9 the process:

Okay, so I was able to kill truss. :)
I am able to cat an arbitrary file within the directory.
