| |
I rememeber some talk a while ago about having an option of making system beep of "System halted" message is displayed.
Is anyone working on it ? Is there a patch available ?
Also can someone tell me the answer to this question:
in kernel/sys.c:sys_reboot we have the following piece of code:
case LINUX_REBOOT_CMD_HALT: notifier_call_chain(&reboot_notifier_list, SYS_HALT,NULL); printk(KERN_EMERG "System halted.\n"); machine_halt(); do_exit(0); break;
I always thought that when I see "System halted" it means I can turn off the computer safely. Is this true ? Why do we need machine_halt() and do_exit(0) instructions ?? Why do we need a call to schedule in do_exit() ?
thank you
