The perf issue seems to be independent and can be reproduced without using any kprobe support. I need to get a simple reproducer and mention it on the linux-perf-user list.

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.
