kernel: [ 0.000000] mtrr_cleanup: can not find optimal value Jun 5 00:20:47 localhost kernel: [ 0.000000] please specify mtrr_gran_size/mtrr_chunk_size Is this some kind of kernel BUG due to the negative value (- 0G) ? MTRR seems to be a topic that is not widely discussed or thoroughly understood when using google to find answers. cat /proc/mtrr reg00: base=0x000000000 ( 0MB), size= 8192MB, count=1: write-back reg01: base=0x200000000 ( 8192MB), size= 1024MB, count=1: write-back reg02: base=0x0c0000000 ( 3072MB), size= 1024MB, count=1: uncachable Many thanks in advance Kind Regards Matt P.S.: I'm not subscribed to the list so please CC me when needed -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
