Shutdown problem
 

Doesn't seem to shutdown properly. I type power off it halts everything unmounts and then it just says 'System shutdown.' or 'Shutdown complete.' something like that anyway (I'll check tonight and post exact message. But it doesn't turn off like it did under redhat.

Is this normal? or is something wrong?

Using Slackware 8.1

Herm try to enable "advanced power management" in your kernel and the "use real time APM bios to power off", I heard sometime this can help.

But I have this problem too, my box doesn't shutdown by it self.... I can reboot, but I can't shutdown... Dunno why.

Yeah exact same problem reboot works fine but not shutdown, very strange!

Thanks for the suggestions, I will look into it and try it out over the weekend...

Just modprobe apm and all should be well.

With a multi-processor kernel ACPI must be used not APM
I haven't tried to get ACPI because I only need a single
processor kernel It works for me. You'll either need to
a) look into acpi and disabling apmd.
b) dissabling multiprocessor support in the kernel options
c) turn off the power by hand
:) I hope that this was helpful

Thanks guys modrpobe apm fixed it all up. :)

Actually, if you edit the rc.modules file, you'll see a line commented out that enables apm so you don't have to do a modprobe each time. I think this works better.

Yeah I just added 'modprobe apm' to the bottom of the rc.modules file.

I have the exact same Pb under SUSE but nothing has worked for me

euh, guys... it does'nt work for me...

I recompile the kernel (2.4.20) with acpi and apm and the shutdown still does'nt work. When I shut down my computer, everything is turning off and then, it says : "Power down" but it hangs there :(

modprobe apm does'nt work for me, becaus I compiled it in the kernel, and not as a module...

Can somebody help me ???

ccool: some motherboard are just bad and you will not be able to shutdown properly... however, try to enable Acpi alone or Apm alone. Apm will always be taked by default I think, so if you enable it and you motherboard does not support it, it will never use acpi unless you disable APM.

You should not have both APM and ACPI enabled. If you dont have SMP, or a laptop, i suggest using APM. Recompile the kernel, this time including both APM and ACPI as modules, then first modprobe APM, and try to shutdown. If that doesn't work, then reboot, and insted load ACPI and try. If that doesn't work you'll have to recompile again. This time include APM to be built in the kernel, and play with APM options. This can involve a couple of kernel re-compiles, and get very annoying... in the end however, it usually works with only APM, or APM and "use real time bios call to power off"
Good luck

thanks nskl....

I will try that

PS: thanks half_elf, but my motherboard work correctly with windows (and I tried mandrake 8.2 and it was working too..) I should have mentioned that...

still, thanks for your replys, I will try that

Here's a solution that works well for me on more recent Gigabyte (2001+) mobos:
Enable ACPI support:
Then add support for System, Processor and Button (Button is the one that does the poweroff). I compile these directly into the kernel.
On older machines that support APM and which have ATX power supplies I do:
Enable APM BIOS support:
Then enable real mode APM BIOS call to poweroff. I also compile these directly into the kernel.
Note that you have to pick ONE of these methods, it makes no sense trying to use both.

ok, I'll try your solution with acpi, because it did'nt work with apm... :(

"Processor" is the one doing the power off for me... I don't think button can do anything yet, the kernel help says "it can't do anything except show you the button event", or something like that.

However, it's true that any modern mb will use ACPI instead of APM.

Wooohhooo

I did'nt know that the new motherboard were using ACPI instead of APM... So I recompiled my kernel with acpi and remove all the apm modules and Voilà ! Everything worked.

I want to thank you all to help me resolv that problem. I am now one question less stupid :D my slackware 8.1 works like a charm now, thanks

I hated that, I always thought it was a Linux thing!

I guess for most people APM works, either when you compile it normal or when you compile it with the "use real mode APM call for shutdown"

For my system I tried ACPI since it is the newer standard, I compiled ACPI into the kernel and added the system option. In order to get ACPI as an option in 2.4.20 I had to turn on the prompt for development or experimental option. I needed the "system" option of ACPI to get it working, not the processor or power button options.

What I did was what was suggested, compile both apm and acpi as modules and then try one or the other. For APM it was just modprobe apm uncommented in the rc.modules but for acpi I had to add a modprobe line so I stuck it in rc.modules right below the apm stuff, I think the line was: "/sbin/modprobe ospf_system" (sorry I'm booted into Windows now and can't verify it.) If you compile it into the kernel you will not need the modprobe line obviously.

thanks... all I did, to make it work, was to compile acpi right into the kernel... so no modprobe, and the shutdown works perfect ;)

still, tks
