Ok, error reproduced under this conditions:
Notebook: ASUS M6N series
BIOS: 0214
OS: Debian
kernel: 2.6.16
Main battery: plugged in.
AC adapter: connected and charging battery.
System load:
Two virtual machines:
First VM.- Compiling kernel 2.6.19 on gentoo.
Second VM.- Running Molinux liveCD.
Power management: cpufreqd
Observations:
I have configured my cpufreq daemon to set low system performance when the
battery starts charging. As the battery charge increases it enables higher work
frequencies to the CPU. When the battery is almost completely charged, the
system goes into full power because the AC adapter is connected. Then, as I was
compiling the kernel with gentoo in a virtual machine I could see how the cpu
temperature rised up to more than 75C. After a few minutes I could see it
rising above 85C and, as the cpu fan stopped working I could guess the ACPI was
going to die so I changed the cpu frequency manually to 600 MHz and I opend a
konsole to see what was happening. I found on dmesg serveral messages like
this:
Feb 20 11:30:09 azazel kernel: ACPI Exception (evregion-0409): AE_TIME,
Returned by Handler for [EmbeddedControl] [20060127]
Feb 20 11:30:09 azazel kernel: ACPI Exception (dswexec-0458): AE_TIME, While
resolving operands for [AE_NOT_CONFIGURED] [20060127]
Feb 20 11:30:09 azazel kernel: ACPI Error (psparse-0517): Method
parse/execution failed [\_SB_.PCI0.SBRG.EC0_.RWRD] (Node dfeccde0), AE_TIME
Feb 20 11:30:09 azazel kernel: ACPI Error (psparse-0517): Method
parse/execution failed [\_SB_.BAT0.BIF1] (Node dfec9d80), AE_TIME
Feb 20 11:30:09 azazel kernel: ACPI Error (psparse-0517): Method
parse/execution failed [\_SB_.BAT0._BIF] (Node dfec9ee0), AE_TIME
Curiously, when I slow down the cpu speed to 600MHz, the cpu fan started
working again.
Well, I knew my system was going to die, so I made it die (all for the
science) :D, I just changed the cpu to performance (1.6 GHz) and it took 5
seconds to freeze the notebook :(
One more thing I've observed: when battery is charged the BIOS seems to submit
an event which causes this error on ACPI:
ACPI: read EC, OB not full
ACPI Exception (evregion-0409): AE_TIME, Returned by Handler for
[EmbeddedControl] [20060127]
ACPI Exception (dswexec-0458): AE_TIME, While resolving operands for
[AE_NOT_CONFIGURED] [20060127]
ACPI Error (psparse-0517): Method parse/execution failed
[\_SB_.PCI0.SBRG.EC0_.RWRD] (Node dfeccde0), AE_TIME
ACPI Error (psparse-0517): Method parse/execution failed [\_SB_.BAT0.BST3]
(Node dfec9d00), AE_TIME
ACPI Error (psparse-0517): Method parse/execution failed [\_SB_.BAT0._BST]
(Node dfec9ea0), AE_TIME
I know it occurs when the battery is charged because this error appeared when
my KDE told me the battery was fully charged. And this is the same error that,
massively produced, makes the system die.
Now I'm going to try to test the 2.6.20-git release as you say in your message.
Thank you for your support :)
