[Bug 561789] Re: Freeze with KMS enabled on Radeon RV350

[moriddin]

Same problems here with an acer travelmate 8000 with an ati mobility
radeon 9600 m10 (rv350)

The login screen appears normal and I can move around with the mouse cursor here. 
After the login i can see the netbook launcher load most of the time and then a few seconds after that the notebook is completely stuck. 
I have to turn the computer off by holding the power button down for a hard power off.

I've tried all the things that are mentioned in this thread:
radeon.modeset : no change at all in behavior
kernel nomodeset : X is completely black with only a pink square following the cursor.
normal text boot (through recovery) and start gdm : x loads and the computer freezes like before.

The only work around that worked for me was to just use the vesa driver
(slow but stable).

Some extra info:
Last week I tried to upgrade from 9.04 to 9.10 and then 10.04 however this problem appeared in 9.10 so I tried a clean lucid install after it. Too bad this didn't work out either. 

Since the computer is completely unresponsive (also over network) I have
no idea how to get a helpful errorlog. Also the system doesn't mention a
bad shutdown.
