 Posted: Fri Aug 20, 2004 7:41 pm Post subject: 2.6.7 P4@2.6Ghz + SMP activated, but only one CPU |
 |
|
I installed Gentoo the first time from the live CD 2004_2 and stage 3 with genkernel. Remember: installed the first time, to see if it is ok for me.
Now, I ran make menuconfig in /usr/src/linux and changed the Processortype to P4 and checked the SMP and SMT Option. CPUinfo is checked, too.
But, however, I can't get my "second" processor working.
cat /proc/cpuinfo tells me, processor:0
/sys/device/system/cpu schows only one folder "cpo0"
Others have cpu0 + cpu1
GKRellm2 shows only one CPU.
What did I wrong?

Making sure:
You recompiled your kernel right? Then copied the new kernel to /boot? And configured the new kernel to boot in grub? And rebooted to the new kernel?
Also:
what number of cpus did you set? |

Yes, I compiled the kernel with "make" as "make menuconfig" suggested after saving the configuration. This takes about some time.
After that I made "make install" and rebooted.
I set 2 cpus.

| So you didn't configure grub or lilo to boot your newly installed kernel. For grub, you must edit your /boot/grub/grub.conf file (I don't know for lilo). Also check that your boot partition was mounted when you did make install. |

THIS seems to be whats wrong! The files in /boot are older than the last compilations I did! My config file changed (/usr/src/linux) but make install didn't copy the new kernel to /boot because I (however) didn't mount my boot partition!
Thank you very very much! You just made a german gentoo-user lucky!
