Subject: p4-clockmod reports frequencies faster than CPU
Date: Mon, 21 Aug 2006 17:11:11 +0100	[thread overview]
Message-ID: <44E9DB1F.2020405@gentoo.org> (raw)

Hi,

A Gentoo user at http://bugs.gentoo.org/141234 reports that the 
p4-clockmod cpufreq driver reports bad frequencies for his 1300mhz 
Pentium 4 processor:

# cat sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
525000 787500 1050000 1312500 1575000 1837500 2100000

The last 3 are obviously wrong.

Unfortunately as this is a production system it's not easy to test other 
kernels, so this has only been reproduced on a Gentoo-patched 2.6.16. 
However the Gentoo patches don't modify cpufreq at all and are generally 
quite minimal.


/proc/cpuinfo output is here:
http://bugs.gentoo.org/attachment.cgi?id=92370&action=view

Does any more info need to be provided?

Thanks,
Daniel
