Unfortunately, the r600g helper thread doesn't set a distinctive thread name.
Please attach (as opposed to paste) the output of 'thread apply all bt' in gdb
when setting RADEON_THREAD=0.

With the environment variable set prior to X (in .bashrc). Running game with
gdb still locks up GPU.

No crash in game reported (break within gdb):

Reverting patch does stop the lockup.

I will test RADEON_THREAD=0 and confirm w/ gdb running the game.

--- Comment #6 from Michel Dänzer  ---
So current Mesa Git master is still affected by this problem, and reverting
commit 7b4276d7acf2e0f77044cb50caa6ad936fa78786 on top of that works around it?

Does setting the environment variable RADEON_THREAD=0 work around the problem?
If not, please attach gdb to the Second Life process to make sure the
environment variable takes effect, i.e. there's no CS helper thread spawned by
the r600g driver.

Bug ID: 86864
   Summary: [rv6xx] RADEON_FLAG_GTT_WC causes GPU to reset when
playing Second Life / other games
   Product: Mesa
   Version: git
  Hardware: Other
OS: All
Status: NEW
  Severity: normal
  Priority: medium
 Component: Drivers/Gallium/r600
  Assignee: dri-devel at lists.freedesktop.org
  Reporter: shawn.starr at rogers.com

I've git bisected from git master and came up with this commit that causes GPU
to lock up (DRI driver locks up, I can ssh an reboot the laptop cleanly
however).

Kernel: 3.17.2-300.fc21.x86_64

[root at devbox mesa-20141127]# git bisect good
7b4276d7acf2e0f77044cb50caa6ad936fa78786 is the first bad commit

r600g,radeonsi: Always use GTT again for PIPE_USAGE_STREAM buffers

Putting those in VRAM can cause long pauses due to buffers being moved
into / out of VRAM.

With this reverted from this point back to Sept 7th, I have stability with the
r600g DRI driver.
