Description John Mizell 2005-09-16 11:00:54 EDT
Description of problem:
Anaconda does not configure AMD64 processor to do cpu frequency.
My processor would only run at 800 mhz but it has the capiblity to switch to
800,1.6, and 2.0 mhz.

Version-Release number of selected component (if applicable):
Version that ships with fedora core 4.

How reproducible:

Steps to Reproduce:
1.Install anaconda on an amd athon 64 cpu
Actual results:
processor operating consitantly at 800 mhz.

Expected results:

processor operating at 800 or 1.6 or 2.0 mhz depending on the load.
Additional info:

I edited /etc/cpuspeed.conf 
added DRIVER="powernow-k8" to the file.

can you retry with the current errata kernel ? (There's actually a new one thats
due to be pushed hopefully in the next few hours at
http://people.redhat.com/davej/kernels/Fedora/FC4/ )
Comment 4 John Mizell 2005-10-05 14:18:39 EDT
I commentted out the entries of /etc/cpuspeed.conf. Then tried with kernel
2.6.13-1.1526_FC4 and no luck. 
Comment 5 Christian Iseli 2007-01-22 06:12:03 EST
This report targets the FC3 or FC4 products, which have now been EOL'd.

Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?

Comment 6 Jarod Wilson 2007-01-24 10:31:04 EST
This works quite well on multiple Athlon64 and Opteron systems under FC5 and
FC6, so I'm going to go ahead and close this bug.
