Hi. I've found by git-bisect that this commit causes problems with glxgears and other stuff:

24b1206ab2dcd506aaac3ef656aebc8bc20cd27a is the first bad commit

    r600g: rework flusing and synchronization pattern v7


The glxgears picture is crippled with no animation.

that's mesa runtime error:
> radeon: The kernel rejected CS, see dmesg for more information.

That's what kernel driver says:
> [20056.450057] [drm:evergreen_vm_reg_valid] *ERROR* Invalid register 0x8040 in CS

System is 64-bit debian.

Build flags are:
PKG_CONFIG_PATH=/opt/lib/pkgconfig ./autogen.sh --enable-texture-float --with-dri-drivers="" --prefix=/opt --with-gallium-drivers=r600 --enable-debug

llvm is 3.2 from tstellard's branch (HEAD: 15265bc80edeceb5bcfc4d0b85be751be9275a7d )
Comment 1 Dmitry Cherkassov 2012-12-24 19:21:21 UTC 
Forgot to add:
* The device is Radeon HD 6970 (cayman)
* Kernel is 3.7.0-rc5 (tip of Alex's drm-fixes-3.7 branch)
