linux-image-2.6.30-rc8-686 fixed my problem. /proc/mtrr now looks like: reg00: base=0x000000000 ( 0MB), size= 256MB, count=1: write-back reg01: base=0x00ff00000 ( 255MB), size= 1MB, count=1: uncachable reg02: base=0x0f0000000 ( 3840MB), size= 128MB, count=2: write-combining I had: 2.6.28: reg00: base=0x000000000 ( 0MB), size= 1024MB, count=1: write-back reg01: base=0x03ff00000 ( 1023MB), size= 1MB, count=1: uncachable /proc/mtrr in 2.6.29: reg00: base=0x000000000 ( 0MB), size= 1024MB, count=1: write-back reg01: base=0x03ff00000 ( 1023MB), size= 1MB, count=1: uncachable reg02: base=0x0e8000000 ( 3712MB), size= 128MB, count=2: write-combining Notice the 1024 MB changed to 256 MB.
