OK, I build booted and installed a kernel with your patches. I also
installed the latest perf code from linus/master. Then I ran the
following:

# perf record -e ftrace:function ls

and then ran

# perf report

It went into an infinite loop of "Processing time ordered events".

Is this expected?

Although perf script works fine.
