I've always checked through SSH from a second machine.
Now for your glxgears test: reclocking works (in Portal 2 as well, where I get
58-60 FPS now). The only difference is the radeon.dpm=1 on the kernel command
line. Was that expected? I thought DPM was activated automatically with your
3.17 branch (it says so during boot as well, see e.g. <span class=""><a href="attachment.cgi?id=103996" name="attach_103996" title="dmesg output">attachment 103996</a> <a href="attachment.cgi?id=103996&action=edit" title="dmesg output">[details]</a></span>) or at
least I interpreted the "[drm] radeon: dpm initialized" line that way.
As far as I'm concerned this can be closed, though the radeon man page should
probably get a line like "setting radeon.dpm=1 is mandatory for reclocking on
the following ASICs". I let you decide whether this is something that should
have happend automatically (my preference) or that requires the kernel
parameter and close/keep the report accordingly.</pre>
