             Bug #: 50857
           Summary: Invalid command stream with CAICOS when ColorTiling2D
                    enabled
    Classification: Unclassified
           Product: Mesa
           Version: 8.0
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: rankincj at googlemail.com


This might also be a bug in Linux kernel or radeon_drv.so.

Just upgraded my 64 bit HD6450 machine to Fedora 17, and gnome-shell fails
immediately (login screen). Disabling ColorTiling2D in xorg.conf fixes it.
ColorTiling2D worked OK - or did nothing - in Fedora 16 with radeon_drv.so from
git and 3.3.7 kernel.

dmesg log and lspci output are attached.
