laptop suddenly poweroff during building ports :: ACPI errors in /var/log/messages

[Joao Macaiba]

Hi.

I'm running FreeBSD 5.4 on a Toshiba Satellite A70-S249. It has a x86 
arch with a Pentinum IV mobile.

It happened three, four times, only during a heavy processing activity 
(running gnome, kde ports).

The error lines are all the same :

--- snip ---
... kernel: ACPI-0356: *** Error: Region EmbeddedControl(3) has no handler
... kernel: ACPI-1304: *** Error: Method execution failed 
[\_SB_.EPWR.PCLK] (Node 0xc1ccd900), AE_NOT_EXIST
... kernel: ACPI-1304: *** Error: Method execution failed 
[\_SB_.PCI0.LPC0.EC0_._Q1E] (Node 0xc1d1f9e0), AE_NOT_EXIST
--- snip ---

I disabled ACPI at /boot/loader.conf, by adding

exec="unset acpi_load"


Now I can run the ports and everything goes fine.

Does this error have to do with ACPI system as a whole or only with a 
part of it ?

TIA,
