When the 'cpuspeed" service is started by "service cpuspeed start" and the
corresponding 'chkconfig' line for 'cpuspeed' is set to "off" for all
levels, the system reboots. I run this system at "level 3".
I copied a kernel OOPS that displayed in my SSH session to the very bottom
of this email.
Is "cpuspeed" not supported on this processor? Is this a bug?
Please reply directly to me since I do not subscribe to any kernel mailing
lists.
Some Important Details
----------------------
Fedora Core 13: 2.6.33.6-147.2.4.fc13.x86_64
[root@xx ~]# cpuspeed -h
cpuspeed v1.5
[snip]
"/etc/sysconfig/cpuspeed" details:
GOVERNOR=ondemand
No "MIN_SPEED" or "MAX_SPEED" values are set (default), allowing the CPU
to report it's MIN and MAX values. When these values are set
(MIN_SPEED=1000000 MAX_SPEED=2800000) the system still reboots when the
"cpuspeed" service is started.
