The patch doesn't help I'm afraid.

/proc/mtrr is:

reg00: base=0x100000000 (4096MB), size= 512MB: write-back, count=1
reg01: base=0x00000000 (   0MB), size=2048MB: write-back, count=1
reg02: base=0x80000000 (2048MB), size=1024MB: write-back, count=1
reg03: base=0xc0000000 (3072MB), size= 256MB: write-back, count=1
reg04: base=0xd0000000 (3328MB), size= 128MB: write-back, count=1
