It's an indirect function call (i.e. the (*call)(); line) to the address 
specified in the CTR register.  You need to find out the value of *call 
in order to figure out which function is failing.  There are probably 
only a small number of possibilities that are actually configured into 
your kernel (look for console_initcall in files that get built for your 
target).
