[Bug 36014] Re: kernel can't scale cpu frequency

[Constantine Evans]

The severity was probably bumped because:

* The bug now affects both the 386 and 686 kernels. Thus there is no workaround listed in the bug.
* Instead of having the frequency stuck at the *highest* value, the frequency is stuck at the *lowest* value on affected machines. In my case that means I am always running at 600MHz instead of 1.6GHz, which causes a very noticeable performance hit.

** Summary changed:

- kernel 686 can't scale cpu frequency
+ kernel can't scale cpu frequency

** Description changed:

- Linux kernel 686 can't scale cpu frequency. I have tested it on two machines one P4 ULV and a standard P4 M with 1.8 ghz and both times it doesn't work. All modules are loaded and it shows under sys the correct min and max value but you can't change it and powernowd too.
- With 386 scaling works fine.
