acpi confusion, redux

[seth vidal]

So if the release notes are accurate then acpi is only on for device
enumeration, hence my problems. That must mean that the heat was either
1. coincidental
2. all in my head
3. something very bizarre.

does anyone else have an Xseries ibm laptop and would like to confirm
this?

Thanks

no, the heat is there because your laptop requires acpi power management
- no power management, the laptop gets hots, and the battery life is
very short.  the laptop may even suffer permanent, severe damage if it
runs too long without power management.

more information from other x23 owners can be found here:

It seems like apm is on for power mgmt.

when I cat /proc/apm it's there.

I got the part about acpi only being on for device enumeration from the
red hat release notes for severn.

hmm, weird - i looked up your laptop (thinkpad x23, yes?) and I read
it's only ACPI - perhaps the site I read was simply wrong.  are you sure
APM is actually working (i.e., it sees your battery, is handling
throttling/power-control, etc.) ?

also, did using acpi=off fix your sound card issue?

$ apm -m
AC off-line, battery status high: 99% (141 min)

looks like it.
it's always been happy under 7.3, 8.0 and 9

yes.

Sorry, enabled only for the purpose of device enumeration.

Enabling it still has the effect of disabling APM.

You probably want to load some of the ACPI modules:
/lib/modules/2.4.21-20.1.2024.2.1.nptl/kernel/drivers/acpi/ac.o
/lib/modules/2.4.21-20.1.2024.2.1.nptl/kernel/drivers/acpi/battery.o
/lib/modules/2.4.21-20.1.2024.2.1.nptl/kernel/drivers/acpi/button.o
/lib/modules/2.4.21-20.1.2024.2.1.nptl/kernel/drivers/acpi/fan.o
/lib/modules/2.4.21-20.1.2024.2.1.nptl/kernel/drivers/acpi/processor.o
/lib/modules/2.4.21-20.1.2024.2.1.nptl/kernel/drivers/acpi/thermal.o

In particular, I would expect that fan and thermal would be important
to you.
