Actually this bug appeared first in Mesa 10.3.2:
http://cgit.freedesktop.org/mesa/mesa/log/?h=3D10.3&ofs=3D100
with this patch:
2014-10-13    r600g,radeonsi: Always use GTT again for PIPE_USAGE_STREAM
buffers    Michel D=C3=A4nzer
http://cgit.freedesktop.org/mesa/=
mesa/commit/?h=3D10.3&id=3D64c2bdc334ba472603b1e7cd2c3046cfbce285b6
I reported this finding to Michael and he responded with link to this bug h=
ere.
This patch continues to be in later releases so all new mesa releases are
affected on 32 bit Linux.

The quick workaround for mesa 10.3.2 and later on 32 bit Linux is to just
revert this Michael's patch above
OR
add your GPU to  Michael's exclusion patch "drm/radeon: Ignore
RADEON_GEM_GTT_WC on Kabini" attached to this bug report.

Just apply only one of these solutions. I prefer to add my GPU to exclusion
list "drm/radeon: Ignore RADEON_GEM_GTT_WC on Kabini" patch inste=
ad of patching
mesa.

See patch attached here where modified Michael's patch to add my Aruba GPU.=
