Fresh install and only one CPU seen instead of two

[warmachine92]

Hello


i need your help. that's the first time i meet a such issue. I don't understand why my fresh sabayon 7 see only one CPU instead of two on my Evga SR2 MB. on Seven it is ok, Bios too.

That's a serious stopper for me to stay on the gentoo's like distro.

Can you please advice on debugging ?


Thanks you

This is interesting, need more info.
I have ran a few older dell work stations with dual cpu and sabayon/kde Did not have a problem.
What sabayon did you install?
If you open a terminal and run "top" without the quotes, do both show up?

hi. no i see only 12 Cores instead of 24 via htop

hi. no i see only 12 Cores instead of 24 via htop

please run

Code: Select all

# cat /proc/cpuinfo | grep processor

maybe htop is limited to show number cpus

I forgot to reply to one question : i'm using sabayon 7 KDE

warmachine@WARMACHINE-SR2 ~ $ cat /proc/cpuinfo | grep processor
processor : 0
processor : 1
processor : 2
processor : 3
processor : 4
processor : 5
processor : 6
processor : 7
processor : 8
processor : 9
processor : 10
processor : 11

Htop doesn't have limitation. If it has because of screen resolution, it says it.

Edit : For Each Processor i have :

Can it be because of 56XX series ?

i search everywhere and found nothing also i have poor sound quality on amarok (all solution over the net did not help neither) I give up. I gonna try Gentoo again live 11.2. we'll see or i go back to kubuntu

thanks a lot

As you can see from Live USB pendrive Kubuntu 11.10 64 bits

there is abolutely no problem

Regarding sound issue, may i could try to use the same backen GStreamer instead of VLC (see on some topic via google)

[sabayonino]

uhm ... it shows 12 logical processors in a single core instead 2 phisycal cores 12x2=24


Are you running sabayon 32 bits or 64 bits ??

[edit] see http://www.linuxforums.org/forum/kernel ... linux.html

[warmachine92]

i'll double check. thanks for that

edit : According to the output i'm running 64 bits version. BTW i don't understand why when trying to install BOINC, it installed the 6.12.42 (which is 32 bits version).
