The systemtap README includes these words: [...] To run a simple test. # stap -v -e 'probe vfs.read {printf("read performed\n"); exit()}' To run the full test suite from the build tree. # make installcheck [...] The full installcheck suite exercises kprobes some, but not in a stressful mode, like probe kernel.function("*").* {} That's partly because the x86 kernel has never been able to survive such a test. It would be great if arm kprobes were robust enough. - FChE
