--- Comment #1 from Andy Furniss adf.lists@gmail.com --- Testing further some of the mesa demos are also wrong - not that I have re- bisected, just assume same issue, on heads -
gloss = blank.
gears, fbo_firecube, gearbox = too dark.
shadowtex = shadow misaligned

Hi,
there is a bug that makes mesa change bank_swizzle if they are provided by backend, can you apply this patch on top of "R600: Packetize instructions" commit and see if you can bisect further ?

Sorry, I tested previous patch and it didn't work.
However this new patch should fix gears, and probably others tests too. (Apply it on HEAD)
