dmesg output

Hello
I have some heavy flickering on my notebook screen.

Chipset: GT215 (NVA3)
Family : NV50

During a chat on IRC I got notice about the "disp/nv50-: fix push buffers in vram" patch which I also applied to the kernel.

http://cgit.freedesktop.org/~darktama/nouveau/commit/?id=1c27bd1522d33075c9d9b625182530ea2bffd09b

After building a custom kernel with this patch applied the problem is still there.

Is there anything else I could do?

Sorry, NVA3 + GDDR5 is known to have issues, and they stand as-yet unresolved. However it used to insta-lock-up, now you just get flickering :) Unfortunately it's a rare combination, although a (the?) key developer now has one in his hands. But he's been busy with other things.
