Resource map sanity check conflict on ACPI Non-volatile Storage

[Leandro Lucarella]

Hi. I've just upgraded to Linux 2.6.28 and when my system boot up I get
this warning:

resource map sanity check conflict: 0x1dffff00 0x1e0000ff 0x1dfff000 0x1dffffff ACPI Non-volatile Storage

And then a stack trace. Should I be worried? (please Cc me)

Here is the trace:

The tolling of the iron bell
Calls the faithful to their knees
To hear the softly spoken magic spells.
