Gpu crash dump and Xorg log

I am running a debian/sid linux on a laptop with an optimus nvidia card 
(nvidia GeForce GT 640 2GB) using the NOUVEAU driver.

>From time to time kwin crashes. 

Also, while running, the cursor sometimes turns to a 2cm X 2cm white block.

Following is the message from dmesg. 

The GPU crash dump and the Xorg.0.log is attached.
