Comment 3 for bug 367774

Just for the record, I too am seeing this behavior (Gigabyte GA-X48-DS4 motherboard). However, I don't see it with an ASUS P5E motherboard (all the other components being the same, swapped to test the different motherboard).

Also, if I run memtest86+ for a few seconds (just long enough to make a complete test of all memory addresses) before booting into Linux, then I don't see any EDAC errors reported.

It seems as if Linux is attempting to read memory before it has been written (possibly due to pipelining attempting to read addresses that are not actually going to be needed?).

Does anyone know if it is the responsibility of the BIOS to initialize all memory, or if the OS ought to be doing this?
