Can't reproduce it any more as of git-8841c2cda51d, but I don't know which
commit actually fixed the bug.

Since the game needs OpenGL 4.1 I have 

  export MESA_GL_VERSION_OVERRIDE=4.1

okay reproduced it with cayman needed a 32-bit build,

it dies in a compute shader invocation alright.

Do you have version overrides, and does it still happen as I got the game, and
it doesn't seem to be killing my redwood.

A trace can be found at: 

https://www.dropbox.com/s/ctkq3b7l9wp05oy/bioshock.i386.trace.xz

Creating it had some warnings: 

apitrace: warning: _gl_param_size: unknown GLenum 0x90DF
[ more of the same ]
apitrace: warning: _gl_param_size: unknown GLenum 0x90DF
apitrace: warning: glMapBufferRange: MAP_COHERENT_BIT|MAP_WRITE_BIT
unsupported 
apitrace: warning: glMapBufferRange: MAP_COHERENT_BIT|MAP_WRITE_BIT
unsupported 

And actually replaying the trace failed for me with: 

error: context mismatch: expected OpenGL 1.0, but got OpenGL 4.1 core

Bug ID: 104665
   Summary: r600: computer shaders break Bioshock on barts
(bisected)
   Product: Mesa
   Version: git
  Hardware: Other
OS: All
Status: NEW
  Severity: normal
  Priority: medium
 Component: Drivers/Gallium/r600

With the commit enabling compute shaders for BARTS

r600/cs: add compute support to caps

Bioshock inifinite starts to lock up at startup (after the intro videos). 

dmsg: 

radeon :01:00.0: ring 0 stalled for more than 10272msec
radeon :01:00.0: GPU lockup (current fence id 0x00063ff9 
 last fence id 0x0006400c on ring 0)
radeon :01:00.0: failed to get a new IB (-35)
[drm:radeon_cs_ioctl [radeon]] *ERROR* Failed to get ib !
radeon :01:00.0: failed to get a new IB (-35)
[drm:radeon_cs_ioctl [radeon]] *ERROR* Failed to get ib !
radeon :01:00.0: Saved 599 dwords of commands on ring 0.

The program doesn't require compute shaders, but when they are available they
are used, hence what ever causes the GPU lockup only gets hit when the caps are
reported.
