Command line used to create the file: > perf record -e raw_syscalls:* -e sched:* -p 2271 -g -- sleep 5 Seems to be an artifact of older kernels. Definitely occurs for 2.6.34 and WindRiver Linux 4. Also reproduced with vanilla 2.6.35. Use newer perf command -- e.g., 3.11 -- to record events and then try to analyze with Linus', Arnaldo's or Ingo's latest branch which now have this patch. Given the breakage it needs to be either fixed or reverted before 3.12 David -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
