Description Tom "spot" Callaway 2002-12-25 22:44:19 UTC
Description of problem:

No APM in Phoebe kernel. This is a severe problem on hardware without ACPI (or
working ACPI implementations). Example: My Dell Inspiron 4000, which uses APM. I
now have 0 power management.

Enabling ACPI is good, but not at the cost of APM.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Boot.
2. Notice that I have no power management.
Actual results:

No power management.

Expected results:

Power management.

Additional info:

Is there a reason that APM was stripped?

Comment 1 Tom "spot" Callaway 2002-12-25 22:59:19 UTC
Addendum: ACPI doesn't seem to work on this machine either, there is no
/proc/acpi structure created. I can attach dmidecode and acpidmp if needed.

Comment 2 louisgtwo 2002-12-25 23:17:45 UTC
the ACPI modules do not load automatically. You can recompile the kernel with
acpi in, or modprobe the modules which should be done in the initscripts. Even
then ACPI has limited power saving features until kernel-2.5/2.6 shows up with
the new driver model.

Comment 3 Warren Togami 2002-12-26 07:02:35 UTC
Well, the kernel does have APM.  When I type "dmesg" these two lines are within.
apm: BIOS version 1.2 Flags 0x03 (Driver version 1.16)
apm: overridden by ACPI.

My computer does support ACPI though.  Perhaps there is some bug where APM
doesn't engage with ACPI isn't available.

Comment 4 Bill Nottingham 2002-12-31 05:33:36 UTC
ACPI is enabled by default. You can boot with acpi=off.

Comment 5 John Coonrod 2003-01-12 03:14:02 UTC
This is very odd. When I look at the "services" it shows apmd ticked. But if I
enter "apm" from the terminal, it says "No APM support in kernel" - so what's
the deal? For laptops (mine is ibm x21) what's the good of having a linux that
doesn't support apm?
