Nope, that's way before you get the fail. initcall_debug might get you the right answer, but I suspect its the intel_uncore driver. I see arch/x86/kernel/cpu/perf_event_intel_uncore.c:uncore_type_init() do exactly what TJ says, its dynamically allocating struct attribute. Now, let me try and trigger that locally, that should not be skylake specific at all. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
