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...)

I tried with kernel parameters:
radeon.hard_reset=1 radeon.audio=0 radeon.dpm=1 radeon.lockup_timeout=20000

But none of them seems to have any effect. 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).

Here are revelant informations:

I know i use a not stable mesa version. It was a last try. But appears also in
mesa 11.1.2...
