[SOLVED]CPU Intel i3-2125 and Linux Mint Debian(3.2.0-2-486)

Postby dmytroche on Sun Jun 17, 2012 5:32 am

Hello everyone,

I've got Intel i3-2125 CPU and installed the Linux Mint Debian (3.2.0-2-486).

As you can see from the CPU's specification http://ark.intel.com/products/59080/Intel-Core-i3-2125-Processor-%283M-Cache-3_30-GHz%29 it has 2 cores and 4 threads.
But when I run cat /proc/cpuinfo I've got the following output:
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 42
model name : Intel(R) Core(TM) i3-2125 CPU @ 3.30GHz

Is it correct behavior for the mentioned version of Linux Mint?

Thanks in advance!
Have a great day.

Linux Mint is funded by ads and donations.

it's correct for that kernel:
Multi-core and multi-CPU support in 32-bit kernel

To guarantee compatibility with non-PAE processors, the 32-bit versions of Linux Mint Debian come with a 486 kernel by default. This kernel does not support SMP, and as a consequence is only able to detect one core and one CPU. If your CPU has multiple cores, or if you have more than one CPU, simply install the 686-PAE kernel and reboot your computer.

Thanks a lot, zerozero

I've just installed appropriated kernel image and that works.
I've solved the problem by sudo apt-get install linux-image-3.2.0-2-686-pae

not a problem 8) anyway you should also install the headers: if you want to use proprietary blobs (nvidia, ati), virtualbox, some wireless drivers (thinking about broadcom) you need it at compiling time.

good luck.
