Before running startx, I can dmesg and see my hardware. cat /proc/mtrr shows me: reg00: base=0x00000000 ( 0MB), size= 128MB: write-back, count=1 reg01: base=0x08000000 ( 128MB), size= 64MB: write-back, count=1 reg02: base=0x0c000000 ( 192MB), size= 32MB: write-back, count=1 reg03: base=0xe8000000 (3712MB), size= 64MB: write-combining, count=1 reg05: base=0xe8000000 (3712MB), size= 64MB: write-combining, count=1 After getting in X (which runs fine), dmesg tells me no less than 491 times that: mtrr: no more MTRRs available # cat /proc/mtrr reg00: base=0x00000000 ( 0MB), size= 128MB: write-back, count=1 reg01: base=0x08000000 ( 128MB), size= 64MB: write-back, count=1 reg02: base=0x0c000000 ( 192MB), size= 32MB: write-back, count=1 reg03: base=0xe8000000 (3712MB), size= 64MB: write-combining, count=1 reg04: base=0xe1ee0000 (3614MB), size= 64KB: write-combining, count=1 reg05: base=0xe8000000 (3712MB), size= 64MB: write-combining, count=1 reg06: base=0xe1ed0000 (3614MB), size= 64KB: write-combining, count=1 reg07: base=0xe1ec0000 (3614MB), size= 64KB: write-combining, count=1 I feel that I need to turn something off (maybe a Module?) in my XF86Config file but unsure which. Any suggestions?
