MSI Mobo--no AMP or ACPI support!?

ming0 · 03-27-2005, 04:11 AM

Hey, I'm using Ubuntu Hoary, and have everything up to date. I also have the acpi daemon set to run at boot.

I just upgraded to an MSI Neo2 FISR (with the 865PE chipset). I'm using a P4 3.2E, and some new memory. Other that, my setup is the same as before (when I had a dual AMD board), only now, when I use the halt command, the computer won't shut all the way off! It just says something like, "power off" and then sits there.

This is kind of bad; I have lm_sensors set up to halt the machine if the temps go above 83 degrees--which is necessary, since I have a watercooling system, and if my pump dies while I'm not home, then my entire system goes with it.

I looked in BIOS, and I seem to have the necessary stuff selected.
Here's what my problem looks like:

Code:

dean@dim:~$ lsmod |grep acpi pcc_acpi 11008 0 sony_acpi 5928 0 
dean@dim:~$ lsmod |grep apm 
dean@dim:~$ sudo modprobe apm Password: FATAL: Error inserting apm (/lib/modules/2.6.10-5-686/kernel/arch/i386/kernel/apm.ko): No such device

Do I need to totally unload acpi before I can turn APM on?

Thanks in advance

add acpi=off to the boot options

Should my grub boot section look like this?

title Ubuntu, kernel 2.6.10-5-686
root (hd0,1)
kernel /boot/vmlinuz-2.6.10-5-686 root=/dev/hda2 ro quiet splash acpi=off
initrd /boot/initrd.img-2.6.10-5-686
savedefault
boot

When I tried this, the system froze indefinitely when it reached the "loading hotplug subsystem" of the boot sequence.

My guess would be to totally disable APM, mean to remove it from kernel and to give "apm=off" in boot option. APM is old and evil, I doubt you need this to power off anyways, you computer is quite new. ACPI is the new standard and a lot of hotpluggable devices (like USB or PCMCIA) now use it (that would explain why you hang while trying to to load hotplug without ACPI).
You can't use both (APM and ACPI) at the same time, if you do, APM is always choosen by default. A lot of distro come with both installed, you better check this out

I am still having this problem, but I know that it can be fixed, because halt works just fine with knoppix. I tried using synaptic to completely remove ACPI and all the config files and then re-install, but it didn't seem to help.

I checked the BIOS, and APM is off, while ACPI is on.

I might just give up and re-install
