Hi, Using debian, actually with linux 4.5-rc7 kernel. (bug also present in 4.4). When i use DRI_PRIME=1, with dri3 enabled (or not) and unigine valley benchmark, the computer freeze. Here are the only kernel log available (as whole pc freeze, i activated netconsole...)

Note that differently to other bugs i could find on the tracker, the computer is completely frozen. Card is a HD 5870 vapor x. It works using a 4x pcie slot. (16x is used on a vga-passthrough configuration, but not used during this test).

It was a last try. But appears also in mesa 11.1.2...
Does a lower Xorg version work better?
Right now, retrograding work is a bit a pain.. I will possibly try with a livecd...
Hi, same problem here on Radeon HD7850. Unfortunately it seems to be kind of unpredictable yet, sometimes I can run a game for hours and it is rock solid, but sometimes I have to restart the system couple of times and it freezes in a row. However, I have a feeling, that more demanding graphics bring the GPU to freeze faster and more often. I also attached myself via ssh from another machine to be able to analyse it. Currently my system is running xorg-server 1.18.3, but older versions did freeze also. If I activate DRI3 lockups seem to come more often, but as already mentioned, this is not very reliable observation. I'll try to do more accurate analysis, please tell me if you have a hint where to look first please.

May be someone should change the bug subject, because this problem doesn't seem to be only HD5870 related
I forgot the most important part :) I'm using ArchLinux with latest stock kernel: Linux hoth 4.5.1-1-ARCH #1 SMP PREEMPT Thu Apr 14 19:19:32 CEST 2016 x86_64 GNU/Linux
