Hi, Saphex
Thanks for the info.
From the description it seems that there exist the following issues on your
laptop.
a. the warning message
> No handler for Region [ECF2] (ffff81007f859f18) [EmbeddedControl]
[20080321]
> ACPI Error (exfldio-0290): Region EmbeddedControl(3) has no handler
[20080321]
> ACPI Error (psparse-0530): Method parse/execution failed [\_GPE._L02]
(Node ffff81007f861490), AE_NOT_EXIST
This is related with BIOS. Before the EC is not initialized correctly, the
L02 GPE is fired, in which the EC internal register will be accessed(In the
P8XH object).
>Store (P80D, \_SB.PCI0.LPCB.EC.DBGC)
In fact it should be :
If (ECON) {
Store (P80D, \_SB.PCI0.LPCB.EC.DBGC)
}
Of course the above message is harmless. After the EC is initialized
correctly, there is no such warning message.
b. the FAN0 reports to be off although the FAN device is working
From the acpidump we can know that the ACPI FAN0 device is turned on/off
by controlling the CTHT power resource. And it is ridiculous that the CTHT
power resource is controlled by read/writing the CPU throttling register.
>Method (STHT, 0, Serialized)
> {
> Store (0x06, TDTY) //TDTY, THTL is the CPU throttling controll
register
> Store (One, THTL)
It seems that the FAN device is not controlled by ACPI. Maybe it is up to
BIOS.
And this is not the fault of Linux ACPI.
c. EC GPE storm (ACPI: EC: GPE storm detected, disabling EC GPE)
It seems that the EC GPE storm also happens on your laptop. This issue is
related with the hardware. But how to workaround this is in discussion.
Please see this issue on bug 9998/10724/11549/11309.
thanks.
