Bug#613747: bug still observed

[Martin Strauss <martin@clan-strauss.de>]

Hello,
I had the hope that the reported unstablities would no longer occure.
Unfortunally that's not true, it just seems to occure less often.
So even the default amd64 installation with firmware-linux-free  and 
firmware-linux-nonfree and kms enabled makes the system unstable.
As it seems the system hangs between the start of the init process
and the X login, usally the display is frozen with some console output 
with some horizontal pixel distortions.
What would be the next steps that I could to help to make the kms 
enabled mode stable ?
sincerly
Martin Strauß
