             Bug #: 43405
           Summary: Only horizontal lines (snow) display in google
                    earth/glxgears using current r600g on RS780M
    Classification: Unclassified
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: blocker
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: idunham at lavabit.com


All that shows up when I run certain OpenGL programs (glxgears and google
earth, so far) is monochrome blocks with horizontal lines. Not all GL programs
are affected (the other standard tests work fine).
On stderr, I get this message repeated ad nauseum:
radeon: The kernel rejected CS, see dmesg for more information.

dmesg repeats this ad nauseum:

[18811.705536] radeon 0000:01:05.0: z/stencil buffer (2) too small (0x00BF3C8F
12240 1 4 -> 3133440 have 3104768)
[18811.705543] radeon 0000:01:05.0: r600_packet3_check:1501 invalid cmd stream
569
[18811.705547] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !

My source tree is updated to the last commit prior to failover removal; that
broke compilation (bug # 43404).  First saw this issue last weekend; I hadn't
seen any issues during August, when I last built mesa; the binaries from then
still work.

Hardware: Radeon HD 3200M - RS780M/RS780MN

Debian squeeze with following packages updated:
Linux 3.0.10
libdrm 2.4.25
libxmu 1.1.0
x11proto-dri2 2.6-2
x11proto-gl 1.4.14
