For D. Hugh Redelmeier: thanks for fix! In fact I have resolved the
issue with 'enable_mtrr_cleanup' boot option:

sudo cat /proc/mtrr
reg00: base=0x000000000 (    0MB), size= 2048MB, count=1: write-back
reg01: base=0x100000000 ( 4096MB), size= 2048MB, count=1: write-back
reg02: base=0x17c000000 ( 6080MB), size=   64MB, count=1: uncachable
reg03: base=0x0d0000000 ( 3328MB), size=  256MB, count=1: write-combining
