problem with 355.11 and debian sid


every time i try the 355.11 driver on my debian sid, i get the following error with blank screen

(EE) NVIDIA(GPU-0): EVO Push buffer channel allocation failed
(EE) NVIDIA(GPU-0): Failed to allocate EVO core DMA push buffer
(EE) NVIDIA(0): Failing initialization of X screen 0

googl’ing for that error gives me many threads about dual graphics or second xserver, but i only have one card and want only one xserver
besides of the x-log there is no other error in any systemlog.

The system is beeping periodic and only accessable via ssh, switch to tty is not possible.

Anything i can check, where is the problem?
