Enabling 'radeon.dpm=1' kernel parameter makes Xorg full crash

[Ḷḷumex03]

When you try to enable 'radeon.dpm=1' parameter into ubuntu linux kernel it makes strange things with display server like: corrupt graphics, screen blinks and other crazy stuff. However, if you try to watch a movie, xorg crashes and you have to restart your computer because you can't run any action, i mean, the screen frezes.

In the other hand, i actually don't know if xorg-server crashes because of 'radeon.dpm=1', or it's radeon driver itself which is crashing xorg-server using 'radeon.dpm=1" parameter.

I'm using a AMD Radeon HD of the 6800 series in Ubuntu Trusty Tahr 14.04.

Ḷḷumex03, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg 1330128

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

As well, given the information from the prior release is already available, testing a release prior to the development one would not be helpful.

Thank you for your understanding.
