best to stay within those tags for now.

 You wrote the problem happens with 9.1.2 but not with 9.1.1, so it's probably
 best to stay within those tags for now.


  I think strage that compiling mAster was on error for me.. Normally aren't

ok, never heard of this git's feature, really nice and useful!
I'll try to bisect when i'll have some spare time.

CB6 is the 6th color buffer and the GPU has a VM page table just like the CPU. 
That info is not really important for you, I mentioned it for other developers.
 If you could bisect mesa using git, that would be great.  There are a lot of
howtos for using git to bisect.  E.g.,
https://wiki.ubuntu.com/X/BisectingMesa

In your case, it would be something like:
git bisect start
git bisect bad mesa-9.1.2
git bisect good mesa-9.1.1

--- Comment #3 from mombelli.mauro at gmail.com ---
I have no idea where to start.
I know how to compile code and debug program, but i have no clue on the
mesa's code structure, and how it works.
I don't know what CB6 is, i'm not sure about page meaning (is it similar to
"classic" RAM page?) etc..
can you tell me at least witch bunch of file/operation i have to debug, and
how?

What you are seeing is a GPU reset.  CB6 is writing to an invalid mapping at
GPU page 0x00014EDB.  Can you bisect the mesa 9.1 branch between 9.1.1 and
9.1.2 to identify the commit that broke it?

What you are seeing is a GPU reset.  CB6 is writing to an invalid mapping at
GPU page 0x00014EDB.  Can you bisect the mesa 9.1 branch between 9.1.1 and
9.1.2 to identify the commit that broke it?

 What you are seeing is a GPU reset.  CB6 is writing to an invalid mapping at
 GPU page 0x00014EDB.  Can you bisect the mesa 9.1 branch between 9.1.1 and
 9.1.2 to identify the commit that broke it?

CB6 is the 6th color buffer and the GPU has a VM page table just like the CPU. 
That info is not really important for you, I mentioned it for other developers.

ok, never heard of this git's feature, really nice and useful!
I'll try to bisect when i'll have some spare time.
