--- Comment #21 from Danylo <danylo.piliaiev at gmail.com> ---
While there is a bisected commit it possibly not a kernel issue, at least half
of it is not in the kernel.

The main issue as i described in previous comment is Mesa trying to allocate
more memory than it itself allows. 

On kernel side the only issue is that the application is being killed the last
even though it holds the most memory.
