hi,
i run current on asus m2400n which works fine most of the time.
but sometimes i get the following errors:

acpi_ec0: <Embedded Controller: GPE 0x1c> port 0x66,0x62 on acpi0
    ACPI-0440: *** Error: Handler for [EmbeddedControl] returned AE_NO_HARDWARE_RESPONSE
    ACPI-1287: *** Error: Method execution failed [\\_SB_.PCI0.SBRG.EC0_.RDC3] (Node 0xc3f80ae0), AE_NO_HARDWARE_RESPONSE
    ACPI-1287: *** Error: Method execution failed [\\_SB_.PCI0.SBRG.EC0_.AIBP] (Node 0xc3f83b00), AE_NO_HARDWARE_RESPONSE
    ACPI-1287: *** Error: Method execution failed [\\_SB_.PCI0.IDE0.CHN1.DRV1._STA] (Node 0xc3f83380), AE_NO_HARDWARE_RESPONSE
    ACPI-0175: *** Error: Method execution failed [\\_SB_.PCI0.IDE0.CHN1.DRV1._STA] (Node 0xc3f83380), AE_NO_HARDWARE_RESPONSE

the result is that hw.acpi.thermal.tz0.temperature increases without 
high cpu load.

i dont know why this happens sporatically. when these errors happen 
i havnt done any special on or before boot.

any ideas ?

thx
regards,
seb
