with disable_mtrr_trim, I get te same:
reg00: base=0xfffe0000 (4095MB), size= 128KB: write-protect, count=1 reg01: base=0xfffc0000 (4095MB), size= 128KB: uncachable, count=1 reg02: base=0x00000000 ( 0MB), size= 256MB: write-back, count=1 reg03: base=0x10000000 ( 256MB), size= 256MB: write-back, count=1 reg04: base=0x1f800000 ( 504MB), size= 8MB: uncachable, count=1 reg05: base=0x1f600000 ( 502MB), size= 2MB: uncachable, count=1 reg06: base=0x1f500000 ( 501MB), size= 1MB: uncachable, count=1 reg07: base=0x00000000 ( 0MB), size= 128KB: uncachable, count=1
Is there any other option ?
cicely:/usr/share/doc/kernel-doc# grep mtrr kernel-par* disable_mtrr_trim [X86, Intel and AMD only]
