Hello

I am testing the new dpm code on my RV730 card:
$ lspci -v
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV730/M96 [Mobility Radeon HD 4650/5165] (prog-if 00 [VGA controller])
	Subsystem: COMPAL Electronics Inc Device 003e
	Flags: bus master, fast devsel, latency 0, IRQ 50
	Memory at d0000000 (32-bit, prefetchable) [size=256M]
	I/O ports at 2000 [size=256]
	Memory at cfef0000 (32-bit, non-prefetchable) [size=64K]
	[virtual] Expansion ROM at cfe00000 [disabled] [size=128K]
	Capabilities: <access denied>
	Kernel driver in use: radeon

The screen constantly flickers, everytime I interact with the computer like moving the mouse og touching the keyboard. If I don't interact the computer, the flickering is alot less. If I boot without radeon.dpm=1, the flicker dissapears.

The flickering is best descripted as if the screen is jumping up and down very fast.

Using the latest ucode for my card:
- R700_rlc.bin
- RV730_smc.bin
- RV730_pfp.bin

Using Xorg edgers in Ubuntu 13.04.

Using Ubuntu drm-next kernel:
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/2013-07-04-saucy/
Git: 69163ea82732894e8c1e17df4010372ed078efdd

Attached dmesg, but there is no errors to be seen.

I have the exact same problem, with the following (mobile) GPU:

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV730/M96-XT [Mobility Radeon HD 4670] (prog-if 00 [VGA controller])
	Subsystem: Dell Device 0272
	Flags: bus master, fast devsel, latency 0, IRQ 45
	Memory at d0000000 (32-bit, prefetchable) [size=256M]
	I/O ports at 2000 [size=256]
	Memory at cfef0000 (32-bit, non-prefetchable) [size=64K]
	[virtual] Expansion ROM at cfe00000 [disabled] [size=128K]
	Capabilities: <access denied>
	Kernel driver in use: radeon
	Kernel modules: radeon

I am using the latest 3.10 kernel, compiled with the latest patches from here: http://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-3.11.
And also the latest firmware available.

I attached the output of "dmesg | grep radeon" on my machine.
