           Summary: r600g: Evergreen segfaults (regression)
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: monraaf at gmail.com


With the new code paths in r600g, everything segfaults on Evergreen cards. The
problem seems to be in evergreen_context_init, in the winsys. More specifically
the /* setup block table */  part. It allocates 472 blocks, but only
initializes block 0 - 467. So any later access to element 468 generates a
segfault.
