Hello,

Can you please copy/paste the output of uname -a on the machine being analyzed? 
The plugin is breaking because the structure proc_dir_entry is not within the 
profile, but I am unable to find any kernels (through 3.13) that do not have 
this structure defined.

I have fixed this in the 2.4 release of Volatility. Attached is a working 
profile for the kernel version. Please let me know if you experience any issues 
with it.
