CPU speed on RedHat

Hi all,
I've installed RedHat 7.3 on Omnibook 6000.After a kernel re-compilation everything works fine but there is a strange thing in the /var/log/messages. The system recognize the CPU#0 as a 250MHz instead of a 650MHz.
Is there anyone can help me?
Thanks.

What does '/proc/cpuinfo' report?

Re: CPU speed on RedHat

Don't believe the kernel is capable of throttling the CPU. Unless you notice any actual slowing of system response, I'd just chalk it up to Redhat's inability to correctly read/report the CPU.

You also may want to check the processor selected in the kernel parameters when you do a make xconfig in the kernel source directory. This is where you will choose the processor you are running on your system.

Hope it helps.

Re: CPU speed on RedHat

The output of /proc/cpuinfo is the same as the one read in the /var/log/messages file.
When I compiled the kernel I choose the PentiumIII/Coppemine CPU type.

Whit the old kernel (I mean the standard one after a clean installation) the CPU speed is correct.Why?
Thanks.

Re: CPU speed on RedHat

Hi

Which version of kernel are you using?
RH has been released 2.4.18-5
http://rhn.redhat.com/errata/RHBA-2002-110.html
You can try both Source RPM & Binary RPM.

And if you want to try some more, official kernel 2.4.19 from www.kernel.org is another choice.

Good luck

Re: CPU speed on RedHat

My kernel version is 2.4.18-3.

Anyway I'll try with 2.4.19.

Thanks.
