Power Off on Halt (fwd)

Subject: Power Off on Halt
I've just upgraded to 2.1.89 from 2.0.34, and I'm pretty amazed with the
new features of this kernel... But, there is a but.
With the previous kernel version my system would POWER OFF on HALT, but it
no longer does that. I compiled the support for it, but it doesn't seem to
work... Any Ideas???

Are you sure that you are running poweroff and not halt?

I have the same problem. The machine (an ATX PPro, VS440FX)
does not power off, although it did it before. It just prints
"System halted." I have tried /sbin/halt -p and
/sbin/poweroff.
This started happening when I compiled a new init (2.72) with
glibc (2.0.6), so the cause could be either init or glibc. (I
suspect glibc.) The kernel is compiled with "APM Power
Management BIOS Support" and "Power off on shutdown".
Has anybody else seen this problem?

Can't be glibc...
I'm having the same problem on a ATX K6 running sysvinit 2.73 and glibc
2.0.7 as well as a Medion Notebook running sysvinit 2.73 and libc 5.4.44.

Read what Andrea wrote. Quote from kernel:
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;
case LINUX_REBOOT_CMD_POWER_OFF:
notifier_call_chain(&reboot_notifier_list,
SYS_POWER_OFF, NULL);
printk(KERN_EMERG "Power down.\n");
machine_power_off();
do_exit(0);
break;
So if you see 'system halted' message, you did not ask system to
powerdown. Fix your userland.
(Or, replace machine_halt() with machine_power_off() :-)

Halt should work!... It did before... Any way, I'm using Slackware 3.4 and
it doesn't have poweroff, just halt...
Just for the record, I'm using a K6 on a ASUS TX97-X board, with an ATX
case...

Yes, I used to have problems too, but saw a "fix" for it on linux-kernel
some time ago. In the file kernel/sys.c there is the function
sys_reboot(), which needs to be "prepared" thusly:
--- /usr/src/linux/kernel/sys.c Sun Mar 15 14:10:17 1998
+++ /usr/src/linux-2.1.88/kernel/sys.c Mon Feb 23 01:31:07 1998
@@ -199,6 +199,7 @@
case LINUX_REBOOT_CMD_HALT:
notifier_call_chain(&reboot_notifier_list, SYS_HALT,
NULL);
printk(KERN_EMERG "System halted.\n");
+ machine_power_off();
machine_halt();
do_exit(0);
break;
(use --ignore-whitespace as i'm using cut'n'paste... if you _really_ want
this patch, i won't recommend on using it)
As you can see this is crude and certainly the wrong way of doing this
since it eliminates the possibility to halt the machine. I can live with
that, though :) I'm using AL440LX, glibc and sysvinit 2.73.
I took a fast look on halt.c (in sysvinit 2.74 package) but couldn't see
why it would fail... It even has a include file of it's own which has
#define BMAGIC_POWEROFF 0x4321FEDC
which matches the definition in include/linux/reboot.h. Where's the
problem?

Now I think you need poweroff:
andrea [at] drago:~/devel/dcex$ dpkg -S poweroff
sysvinit: /sbin/poweroff
sysvinit: /usr/man/man8/poweroff.8.gz
Take a new sysvinit source for example from the debian site:
ftp://ftp.debian.org/debian/hamm/hamm/source/base/sysvinit*.orig.tar.gz
To force a poweroff run:
poweroff -d -f -i

You're all sure, that you use UP kernels?

I had the same problem (you guessed :-) with a 2.1.71 kernel. Solution
(in my case): There´s a #define SMP (or is ist __SMP__?) in the
Makefile, but apm doesn´t work with SMP. Simply comment it out.

No new kernel? Have a look at your boot messages. Maybe it shows
somewhere "No APM support for SMP, APM support disabled".

I upgraded 2.0.32 -> 2.1.84 about a while ago and to 2.1.89 recently, and
experience the same problem. Software config is same as above and neither
halt nor poweroff does a poweroff (only message "System halted.").
Weird.
