Just to clarify, I'm testing with the testsuites/samples/fileio program.
The problems are occurring in the function that displays the menu to the
user.  I'm assuming that at this point everything should be initialized.

Stack size:
I've increased the stack sizes and still have the same problems.  Besides,
stack issues wouldn't explain the following:

   printf("test output\n");    // works fine
   printf("test output");      // locks the processor

printk:
I tried using printk to display a newline terminated text string.  No output
Appeared on the console port but the system didn't hang.

I did find out why the 162 BSP doesn't accept any user input though.  The
char_ready function in console.c always returns false even on success.  Once
I changed the final line in the function to return true then I managed to
get input data to the program.

That's one step further than I was yesterday.
