                    spring
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: pheldens@ziggo.nl
          Hardware: x86-64 (AMD64)

           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

linux 3.10.* and before

crashes in xonotic and spring after indeterminate time, colours the screen with
garbage, does not crash when R600_DEBUG is unset.


all I caught so far is a kernel oops output

--- Comment #1 from David Heidelberger (okias) <david.heidelberger@ixit.cz> ---
these days is R600_DEBUG=sb default, could you retest? Also 3.12 should be
stable enough :)
