leaving 64MB of memory at the top of RAM uncached. What do you want to
bet that something important (kernel code?) is getting loaded there..

So essentially it's a BIOS problem, it's not setting up the MTRRs
properly in order to map all of RAM as cacheable. As Andi says, complain
to Intel.


Could the BADRAM patch be useful for him?
http://rick.vanrein.org/linux/badram/download.html has 2.6.21 version.
It says it supports x86_64. May be using this patch he can exclude
that RAM from being used/accessed?
