No, local_fiq_enable is not visible in the trace. I would say the
problem is after line 546.	

Could you put the compiled code (file vmlinux in the kernel sources
directory) corresponding to the trace in an area where I can download
it? If you compiled the kernel with debug info, it should tell us where
the problem is.
