Hi all,
I am idiot on ACPI knowing nothing about it :)
When I boot linux on AMD Athlon64x2 + A690G + SB600 platform, I get
2 lines of error message saying "Error attaching device data". I've
tested on kernels 2.6.18 ~ 2.6.20, and each of them has the same error.
I debug the drivers/acpi/scan.c and find the error message is dumped
in fuction acpi_device_set_context. and type == ACPI_BUS_TYPE_PROCESSOR,
status == AE_ALREADY_EXISTS. (pls see the following code.)
There are 2 error lines in dmesg because, I think, I use a dual core
CPU.
Any suggestion is very thankful!
--------------- in drivers/acpi/scan.c --------------------
static int acpi_device_set_context(struct acpi_device *device, int type)
{
acpi_status status = AE_OK;
int result = 0;
/*
* Context
* -------
* Attach this 'struct acpi_device' to the ACPI object. This makes
* resolutions from handle->device very efficient. Note that we
need
* to be careful with fixed-feature devices as they all attach to
the
* root object.
*/
if (type != ACPI_BUS_TYPE_POWER_BUTTON &&
type != ACPI_BUS_TYPE_SLEEP_BUTTON) {
status = acpi_attach_data(device->handle,
acpi_bus_data_handler, device);
if (ACPI_FAILURE(status)) {
printk("Error attaching device data\n");
result = -ENODEV;
}
}
return result;
}
--------- dmesg ------------
