Jun 5 00:26:48 localhost kernel: [ 0.000000] please specify

when trying to append some commands, e.g.:

or
enable_mtrr_cleanup mtrr_spare_reg_nr=0
it doesn't make any change

Jun 5 00:20:47 localhost 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
