Created attachment 28972 [details] Picture of the error I have the radeon driver with KMS enabled by default built into the kernel. When I added the "radeon.audio=0" parameter I got the crash from the attached picture. Note: my video card is connected using both it's DVI outputs to the same monitor's VGA and HDMI inputs (using a DVI to VGA adaptor and a DVI to HDMI cable).
If you are still seeing this with a modern kernel please update/re-open the bug - thamks
