Hi everybody,
Laptop: Sony VAIO VGN-SZ3VP/X
Kernel: 2.6.18-4
I have the following problem with mtrr:
#cat /proc/mtrr
reg00: base=0x00000000 (?? 0MB), size=2048MB: write-back, count=1
reg01: base=0x7ff00000 (2047MB), size=?? 1MB: uncachable, count=1
#lspci -v

Can you help me to fix the "uncachable" reg?
Thanks
