Can you pls try the below

I did, here are the logs:
364K http://files.hz6.de/kern_20130724_2.log
I don't understand what exactly this patch does, but I noticed:
- much less drm debug info, resulting in a much smaller log
- no more noticeable lag on my system (even though a storm was
detected).
I double checked the latter and the lag seems indeed to be gone...
