mtrr: your CPUs had inconsistent fixed MTRR settings
mtrr: probably your BIOS does not setup all CPUs

we have 2cpus
but one of them are not enabled...
what shoul I do fix the problem

some messages print mtrr: your CPUs had inconsistent fixed MTRR settings
mtrr: probably your BIOS does not setup all CPUs

Hi,

I know this may sound obvious but did you check your Bios for settings of the MTRR
(Memory Type Range Registers)?

Greetings, Martin

how can I check MTRR?

hi,
to check mttr

cat /proc/mttr
and I have attached a c program that will also
show mttr

But I thing that your problem is probably bios related ...the messages in your message seem to point to this

Hope this helps

I just remember where i got tge c program from

if you do a locate mttr you will probably find something like

#locate mtrr
/usr/share/doc/kernel-doc-2.4.20/mtrr.txt

the kernel version may be different

I have attached mtrr.txt here in case you dont find this on your system

There must be some setting up to do in your bios to enable the use of the 2 cpu's' and registers.

What is your model of your machine and the version of bios that you are using, and if you have already check theses what did this reveal ?
