Description of problem:
I would like to request an update of the speedstep driver for power
management on newer laptops. The current speedstep driver is dated
1/2/03 and has not changed between U2, U3 or U4 beta. I would like to
request an update for U4 final or even U5 kernel such that newer
Centrino-based latops like the IBM Thinkpad T40 and T42 would be
The FC2 2.6.x kernel speedstep driver works well on these laptops, but
we'd like RHEL 3's speedstep driver to also work.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. modprobe speedstep
Actual Results: dmesg shows
cpufreq: Intel(R) SpeedStep(TM) for this chipset not (yet) available
Expected Results: # lsmod | grep speedstep
speedstep 4652 0 (unused)
Older laptops like the IBM Thinkpad T30 work just fine.

This is a feature request. U4 is closed (and in beta), by the way.
Internal RFE bug #137187 entered; will be considered for future releases.
Since I cannot see bug #137187, can I get an update? Is the speedstep
driver being updated in RHEL 3 Update 5? Thanks.
Brian, I've just added you to the cc: list of Featurezilla 137187.
I don't think anyone in Product Management has yet evaluated it.
Thanks Ernie. I saw the CC and asked for an update in the FeatureZilla. :) Do
you want to mark this BZ closed?
Good question. Rob/Suzanne, are we supposed to close BZs that get
associated FZs? Should I close this as a dup of 137187?
Brian, I've just learned that our general practice is to keep
bugzilla reports open as long as their associated featurezilla
requests have not yet been resolved.
What is the status of this BZ? Did a speedstep update get included in Update 5?
Brian - if this is something for which you have urgency, you would be much
better off going through support, as bugzilla is for bug tracking and is not an
avenue for technical assistance or support.
To access support, please go to http://www.redhat.com/support or call 800-REDHAT1
PM ACK for U6
devel NAK for U6
likely there will be numerous TSC issues to work out, too involved and time
consuming to be done by U6
INFO: there is a 2.4.21 patchset that includes cpufreq for centrino. its for the
mainstream kernel but can probably be used to generate a RHEL3 patch
