The options you need to enable to use ftrace are:
CONFIG_FUNCTION_TRACER
CONFIG_FUNCTION_GRAPH_TRACER
CONFIG_STACK_TRACER
CONFIG_DYNAMIC_FTRACE
There's a pretty good tutorial here: http://lwn.net/Articles/365835/
If you are willing to compile your own kernel, can you try going to
the latest 3.5 kernel and see if the problem still affects you there?
