Hi,
i cvsuped around monday morning, and after building / installing, my
kernel said every second or so :

Jul 17 09:48:01 syrenna kernel: ACPI-0438: *** Error: Handler for
[EmbeddedControl] returned AE_NO_HARDWARE_RESPONSE
Jul 17 09:48:01 syrenna kernel: ACPI-1287: *** Error: Method execution
failed [\_SB_.PCI0.BAT0._BIF] (Node 0xc3ccc760), AE_NO_HARDWARE_RESPONSE
Jul 17 09:48:01 syrenna kernel: ACPI-0438: *** Error: Handler for
[EmbeddedControl] returned AE_NO_HARDWARE_RESPONSE
Jul 17 09:48:01 syrenna kernel: ACPI-1287: *** Error: Method execution
failed [\_SB_.PCI0.AC0_._PSR] (Node 0xc3ccc660), AE_NO_HARDWARE_RESPONSE

note that before upgrading, it was saying:

Jul 16 16:44:22 syrenna kernel: ACPI-0432: *** Error: Handler for
[EmbeddedControl] returned AE_ERROR
Jul 16 16:44:22 syrenna kernel: ACPI-1287: *** Error: Method execution
failed [\_SB_.PCI0.AC0_._PSR] (Node 0xc3ccb660), AE_ERROR
Jul 16 16:44:22 syrenna kernel: ACPI-0432: *** Error: Handler for
[EmbeddedControl] returned AE_ERROR
Jul 16 16:44:22 syrenna kernel: ACPI-1287: *** Error: Method execution
failed [\_SB_.PCI0.BAT0._BST] (Node 0xc3ccb720), AE_ERROR


and now with my patch (taken from a recent mail from Nate) it is OK.
THE PATCH : i just changed line 662 : 1000 -> 10000.
as i read in other mails, it should already been changed to 5000 or so.

just to make you notice i had the problem too.

note that i use a custom DSDT (the original worked only with windows, and
i found a page related to linux which has inspired my hack on the dsdt).
KERNEL, dmesg, modified DSDT, and other informations (description of the machine)
are to be found at:
