Will,
Was your test on an smp system?
I've seen this crash once on my F9-Alpha... its a uni-processor system. The test
says its applicable only for SMPs. This test crashes when run during make
installcheck. But, stap -vvv -g pmap_agg_overflow.stp aborts the run with a warning.
I looked at the stap script... it probes scheduler_tick. To just verify I tried
a kprobe module that had a probe on scheduler_tick and it worked without problems.
