OK, my confusion came from all the different things perf can use.  I 
have not yet been able to reproduce the "perf stat" failure, but I do 
see the failure with Steve's example using tracepoints.  I had thought 
that was using kprobes, but apparently it just uses tracepoints.  These 
look like two different failures to me:  One related to tracepoints, and 
one in the PMU driver.

Since this seems unrelated to kprobes I don't plan on pursuing these 
particular problems.
