--- Comment #9 from Mauro Rossi <issor.oruam@gmail.com> ---
Hi Nicolai,

thanks a lot for your commitment and help.

Now I also learned how to run deqp on linux

I confirm that with the llvm 3.8.1 and later I see no GPU lockups.

Being oibaf ppa not affected, the resolution happened between 3.8.0 and 3.8=
.1
and has to be related to SI lowering, that's a lot of useful info for my
problem.

Cheers!
Mauro
