I am working on supporting hot add memory on my box (IBM x445) via the
memory hot plug work that is going and but I am having some trouble with
the acpi event itself. When I trigger the acpi event I get
acpi_bus-0077  acpi_bus_get_device : No context for object
I dumped the status from acpi_get_data and it was 00000005,
I am not too sure where to head with this. What does AE_NOT_FOUND mean?
The call path is
apci_ns_get_attached_data (which returns the AE_NOT_FOUND)
Is the bios not providing some data that is needed to handle the event
or do I need to set something up before the action happens (registering
a handler for the event)? The bios is pre ACPI 2.0. I am relatively
new to ACPI and I would be grateful for any input that points be in the
Kernel is 2.6.12-based.
