R600_DEBUG=sb,sbsafemath,nollvm chromium-browser
Those debugging options only have an effect with the r600g driver, not with radeonsi.
radeonsi isn't the only chipset family affected: intel cards hd2000, hd3000, hd4000; gm45, gm965, i915 (sandybridge, ivybridge, haswell, etc.), or other radeons are also affected in different ways
r600g issues might be related, but most definitely not Intel GPU ones.
