Hi,
i tryed to get a laptop working with the latest acpi-20020815-patch.
but there seems to be a problem with the embedded controller stuff:
My bios doesn't have an ECDT area, so the EC isn't available from
beginning. Later, while scanning the bus, the PNP0C09-EC device is
found, and everyting seems fine. (handlers get attached, and so on).
But till this point, all devices that need an working EC got lost with
following message: 'no handler for region(c14ed128) [Embedded_control]'.
Okay. I figured out the problem, but who's problem is it? Is this a bios
problem (has the EC-device to be listet before any device that needs
EC)? Or has the acpi-implementation to scan for ECs before it starts the
device-walk?
after scanning the net for information i only found out that this seems
to be a wide-spreaded problem...
On request i'll provide all needed information like acpi-table-dump's,
log's, ....
have a nice day,
marvin
