commit b778a563a2762872c0ba05af935b126747579f94 Author: Paul Menzel paulepanter@users.sourceforge.net Date: Tue Feb 11 10:38:27 2014 +0100
intel/fsp_sandybridge/acpi/sandybridge.asl: Increase range length of buffer to 0x8000
Linux kernel 2.6.31 reports the following warning.
resource map sanity check conflict: 0xfed10000 0xfed17fff 0xfed10000 0xfed13fff pnp 00:01
Indeed `src/northbridge/intel/fsp_sandybridge/acpi/hostbridge.asl` contains
OperationRegion (MCHB, SystemMemory, DEFAULT_MCHBAR, 0x8000)
so instead of 16 kB specify that 32 kB are decoded in that memory range.
