Hi and thanks for the help in advance,

Recently , I have tried to recompile my custom kernel and everything works
fine, except apm.o. Whenever I tried to load this module by insmod, the
following error messages will come out and the module failed to load.

Using /lib/modules/2.4.21+helpers/kernel/arch/i386/kernel/apm.o
/lib/modules/2.4.21+helpers/kernel/arch/i386/kernel/apm.o: unresolved symbol
default_idle
/lib/modules/2.4.21+helpers/kernel/arch/i386/kernel/apm.o: unresolved symbol
machine_real_restart

I am using kernel 2.4.21, plus newnet helper patch in this build. Please let
me know if you have the same experience and how to make it work.

Thanks

You are using 'insmod'. Did you try 'modprobe'?
If that fails try compiling the module directly into the kernel instead
of as a module.

Thanks for your help.

Today I have tried install the module by modprobe -v apm and gave the
following result:

Using /lib/modules/2.4.21+helpers/kernel/arch/i386/kernel/apm.o
Symbol version prefix ''
/lib/modules/2.4.21+helpers/kernel/arch/i386/kernel/apm.o: unresolved symbol
default_idle
/lib/modules/2.4.21+helpers/kernel/arch/i386/kernel/apm.o: unresolved symbol
machine_real_restart
/lib/modules/2.4.21+helpers/kernel/arch/i386/kernel/apm.o: insmod
/lib/modules/2.4.21+helpers/kernel/arch/i386/kernel/apm.o failed
/lib/modules/2.4.21+helpers/kernel/arch/i386/kernel/apm.o: insmod apm failed

Other than compiling directly into kernel are there any work around for this
? Since I would like to know why this happens. Is it a bug in apm.o module ?

Thanks
Bosco

Well, find out where it is in the code, and then find out why it isn't
available in your kernel or modules comilations, and then do something
about it. Whassa problem?

Well sometimes I find that some modules on some systems just won't load
separately, but function 100% correctly when compiled into the kernel.
For example: I found this occuring with the button.o and processor.o
module for ACPI in 2.4.22 on my Athlon A7M266 system.

Thanks ! I will try build it into kernel and see if it works ! I have a
question. What do you turn ON for Power Management support usually ? I put
Power Management Support, ACPI support, ACPI Bus Manager and System as build
into kernel only. For the rest of the options like ACPM, I feel that its
more like for laptop after reading their help, then I build them as modules
and load them when necessary. Do you turn ON some other options as well

All from my experience (Athlon TB, A7M266, RH9, 2.4.22 kernel.org): I
need to leave APM support in the kernel. If you also enable ACPI and
your motherboard, cpu and bios support ACPI, the 'dmesg' output will say
that APM is not being used since it using ACPI instead. It says APCI
overrides APM. I also disable APIC, but this I've heard may cause probs
on some systems (P4's included). I need to compile all ACPI modules into
the kernel. However on my laptop (Athlon XP, RH8, 2.4.20+patches) I find
that all the ACPI modules work 100% correctly compiled as modules and
modprobing works correctly.

Not sure what ACPM is, but I guess I might have it as a module. What I
did was I used RH's basic athlon.config profile and left most of the APM
as it was.

Clearly, when I'm using ACPI, I use the 'acpid' daemon, it is
recommended to disable the 'apmd' daemon. I've seen the ACPI suspend
work properly on another athlon system via the pwr button, I have yet to
reproduce this on mine, once done I will put documentation on the web.

Thanks Mauriat !

From your experience, it sounds like Advanced Power Management BIOS support
(sorry for my typo as ACPM before) is not really necessary if you already
complied ACPI into kernel. Probably I will stop loading it by removing it
from ntsysv. It also sounds like APM is more like for laptop and not for
desktop as well. Am I correct ?

Regarding ACPI options, sounds like Button, AC Adapter and Embedded
Controller options are for laptops only. How about processor ? It says it
will use ACPI C2 and C3 processors states to save power, what CPUs have this
features ? I am using intel P2 266.

Thanks again

From what I read APM kernel support is needed for the OS to physically
turn off the hardware in the last part of the shutdown. However the apmd
daemon is not needed for this to work.

You're right, most laptops support APM better, however many laptops do
support ACPI as well. Some older hardware with no ACPI may work better
with APM, however I cannot confirm this.

ACPI compatibility depends on how well the motherboard bios supports it,
as well the states that the CPU supports. Note: most systems do not
implement it 100% compliant with the standards. Some implementations
work much better than others.

I use the Button. The AC Adapter doesn't do much on the desktop, and I'm
still not sure for what the Embedded Controller is used. After you have
ACPI compiled and loaded the 'processor' (either compiled as module or
compiled into the kernel), 'cd' to the '/proc/acpi' directory.

This is from my P3 500, which is closer to yours than my Athlon. Most of
the files tell you everything your system supports.

I haven't played with any P4's or newer P3's, but Athlon XP with
PowerNow (typically in laptops, but possible in desktops) supports
throttling which will reduce CPU clock speed to lower frequency to save
power. Also Athlon and Athlon XP support system suspend. Most of this
info isn't well documented and gathered mostly from people's testing and
experience.

This is all with Kernel 2.4.20 and higher. From what I hear Kernel 2.6
will provide much better support for ACPI and support more states properly.

Thanks Mauriat.

From your /proc/acpi, It sounds like you have turned on most/all of the
options for ACPI support. Let me try turn on the rest if the options and see
what will happen. :-)
