Hi,

Ok, so I am getting the same error message as you. I checked my syslog now. I have my uncoreimc addr=0xfed10000 (after masking) And I also have pnp 00:01 overlapping the imc range completely. What pnp device does it really represent? the DRAM controller? So I think my laptop behaves like yours.

grep -Er . /sys/devices/pnp0/00:01/* 2>/dev/null /sys/devices/pnp0/00:01/firmware_node/hid:PNP0C02 ...

so this PNP0C02 is

[ 0.363943] system 00:01: Plug and Play ACPI device, IDs PNP0c02 (active)

@Rafael, can you please make sense of this whole ACPI gunk?

We have a resource conflict with pnp 00:01, analysis here: http://lkml.kernel.org/r/20140226092903.GA22639@pd.tnic

This is the rest of the 00:01 info from sysfs:
