Public bug reported:
Have a clean install of Hardy on a new Toshiba Dynabook TX/760LS and I
am going through the laptop testing as outlined on Ubuntu
(https://wiki.ubuntu.com/LaptopTesting) and encountered this error. Is
it something that I need be concerned about and if so how do I resolve
it? Thanks.

PowerNowd encountered and error and could not start.
Please make sure that:
- You are running a v2.6.7 kernel or later
- That you have sysfs mounted /sys
- That you have the core cpufreq and cpufreq-userspace
modules loaded into your kernel
- That you have the cpufreq driver for your cpu loaded,
(for example: powernow-k7), and that it works. Check
'dmesg' for errors.
If all of the above are true, and you still have problems,
please email the author: [EMAIL PROTECTED]
