Signal 11 is SIGSEGV.  That it is happening in init is unfortunate as 
that makes it rather difficult to debug.

One approach that I have seen that might be helpful in this situation is 
to modify the Linux kernel so that it prints the ip and faulting address 
to the console before sending SIGSEGV.  Then you would at least know 
where the problem is happening.  Divining why is another matter all 
together.
