question about MTRR areas on x86_64

Hello,

i've got the following error message:

mtrr: type mismatch for fb000000,1000000 old: write-back new: write-combining
i2o: could not enable write combining MTRR

the output of /proc/mtrr is as follows:

reg00: base=0x00000000 ( 0MB), size=8192MB: write-back, count=1
reg01: base=0xe5000000 (3664MB), size= 16MB: uncachable, count=1
reg02: base=0xe6000000 (3680MB), size= 32MB: uncachable, count=1
reg03: base=0xe8000000 (3712MB), size= 128MB: uncachable, count=1
reg04: base=0xf0000000 (3840MB), size= 256MB: uncachable, count=1

Could it be because the machine has too much memory, or is there a bug in the I2O driver?

Thank you very much in advance.


Best regards,


Markus Lidel
