No power off when shutting down RH8

dnar · 01-09-2003, 09:16 AM

I am running the following gear:-

Gigabyte GA-7VAXP mobo
RedHat 8.0
2.4.20 kernel

When I do an init 0, the system does not actually power off when it has shut down. If I drop my "overclocking" hard drive in (Windows lol), it is capable of doing a power off.

I have the following settings for ACPI and APM, do these have any bearing on hardware power down?

CONFIG_PM=y
# CONFIG_ACPI is not set
# CONFIG_APM is not set

Any ideas?

Cheers.

Anyone?

CONFIG_APM=y
I have mine as a module,
CONFIG_APM=m

Thanks Aussie (I must owe you a beer by now, surely).

Read again, I don't have CONFIG_APM defined... Is that required for power off? I am guessing it is...

Thanks.

Yes, you need to define CONFIG_APM, don't worry about all the other options, they are for laptops.
I'll have a coopers :-)

Ok, so built as a module, how does this module get loaded? Do I need to add anything to /etc/modules.conf or does Kudzu detect this as new hardware at boot time and handle it for me?

Ok, Coopers it is, I guess you'll need a bed if your heading over for a beer?

Just put apm into /etc/modules.conf

Rodger that.

Re-compiling now, thanks.

Weird, when I compiled apm as a module, I received "unresolved symbol" errors when doing a depmod -a. I have re-compiled with apm in the kernel (non-modular) and no pro'bs. About to do an init 0 with the new kernel and see what happens.

No joy. When shutting down, I see the apm daemon being stopped, but the system shuts down to the "Power Off" message and that's it... I want the system to actually power off, so that my over-temperature shutdown mechanism will really save the CPU/mobo in the event of a CPU failure.

What happens when you issue the commands halt or shutdown -h "now"?

dnar · 01-10-2003, 02:09 AM

I did not try that. I simply performed a /sbin/telinit 0. I was under the impression that shutdown performed an init 0 anyway, and from the man pages:-

man shutdown:-

Quote:

...shutdown does its job by signalling the init process, asking it to change the runlevel. Runlevel 0 is used to halt the system...

But I will try that later, I just re-connected so I'll stay online for a while and try shutting down again later tonight.

Thanks again Aussie.
