Subject: Bug: Pentium M not always detected by CPUFREQ
Date: Tue, 21 Nov 2006 16:46:29 +0100 [thread overview]
Message-ID: <200611211646.29488.hs4233@mail.mn-solutions.de> (raw)
Hi !
One module thinks that I have a Pentium M, the other doesn't.
Which module is right?
# modprobe p4-clockmod
p4-clockmod: Warning: Pentium M detected. The speedstep_centrino
module offers voltage scaling in addition of frequency scaling.
You should use that instead of p4-clockmod, if possible.
p4-clockmod: P4/Xeon(TM) CPU On-Demand Clock Modulation available
Okay, so I'll try that:
# rmmod p4-clockmod
# modprobe speedstep-centrino
FATAL: Error inserting speedstep_centrino
(/lib/modules/2.6.19-rc6/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko):
No such device

So far I can only say that speedstep-centrino doesn't have an
entry for a CPU with a mere 600 MHz. May this be the problem?
