I get an odd lock up on my imx31ads target when I try to ftp a particular binary onto its file system.  The system 
becomes unresponsive.  I can’t execute any commands through a high prio shell and networking is completely blocked.  I 
am having a hard time debugging what is going on since I can’t get any useful information from my target.  No cores are
 being produced so I assume its just a kernel lockup.   Here is an example of what happens.

Here is a pidin before I actually send the file.  My ksh is running at 80 and you can see the ftp daemon running at 10.

From my Neutrino host I send the binary and back in my shell I try to execute pidin to see what’s happening and this is
 what I see after about 2 mins of waiting for a prompt.
imx31ads-3480# pidin
ksh: pidin: cannot execute - Host is down
imx31ads-3480#

My host Neutrino/linux 642 M2
My target imx31ads 642M2

Any suggestions for fixing / debugging this issue?
