When is that initcall done on your platform? lockup_detector_init is called in a kthread started by the rest_init function. All of that is called after acpi_subsystem_init, sfi_init_late, efi_late_init, and efi_free_boot_services. Also, the dmi code protects itself behind the dmi_initialized variable, so if dmi_check_system is called before dmi_scan_machine is called then nothing bad should happen. On x86, dmi_scan_machine is called from setup_arch, which is well before any of the above functions are called. josh _______________________________________________ kernel mailing list kernel@xxxxxxxxxxxxxxxxxxxxxxx http://lists.fedoraproject.org/admin/lists/kernel@xxxxxxxxxxxxxxxxxxxxxxx
