            Bug ID: 94904
           Summary: [vulkan, BSW]
                    _device intermittent crash
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: idr at freedesktop.org
          Reporter: mark.a.janes at intel.com

This suite of tests crashes intermittently on BSW

repeatedly running the single test
should generate a segfault about 25% of the time.

The stacktrace leaves mesa for libgcrypt at src/util/mesa-sha1.c:190

Mesa initializes libgcrypt on first use, based on a static int.  This is not
sufficient to protect the initialization routine from simultaneous execution. 
Based on
there should be a real mutex here.
