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).
