How do I avoid bad memory?
My kernel is 18.104.22.168 and I have 2 x 512MB memory.
I have a few bad bits that memtest indicates are around the 830MB mark.
I'm told that I can add mem=800M to the kernel parameter list. However that won't work if memory is allocated from highest address down, which I'm told is a possibility.
Does the kernel allocate memory from high address to low, or low to high?
