Re: Signal 8




   i really dont know what this signal is for. But with the help of the 
NIP I think u can see which function iin your application is causing this 
oops. Hoping tha you can enter the atleast ur bash (OR did u say that ur 
application is getting run just after boot before bash) you can exeute 
this command on the object file of the kernel (vmlinux)

 use objdump -dS --start-address=NIP(or u can have some instructions 
before that) --stop-address= (anything after NIP ) (but be sure to narrow 
the range)....

  this will tell u which function is causing this problem. If u have 
another image u can boot with that image and execute this....
