          Priority: medium
            Bug ID: 81404
          Assignee: idr at freedesktop.org
           Summary: [IVB]
                    ES3-CTS.gtf.GL3Tests.framebuffer_blit.framebuffer_blit
                    _functionality_multisampled_to_singlesampled_blit hits
                    assertion failure in blorp
        QA Contact: intel-3d-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: idr at freedesktop.org
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/DRI/i965
           Product: Mesa

On my IVB laptop with current Mesa master (9a723b970), I hit:

Test case
'ES3-CTS.gtf.GL3Tests.framebuffer_blit.framebuffer_blit_functionality_multisampled_to_singlesampled_blit'..
cts-runner: gen7_blorp.cpp:190: uint32_t
gen7_blorp_emit_surface_state(brw_context*, const brw_blorp_params*, const
brw_blorp_surface_info*, uint32_t, uint32_t, bool): Assertion `(fieldval & ~
(((1<<((13)-(0)+1))-1)<<(0))) == 0' failed.
Aborted (core dumped)

This is not a failure that I recall seeing before, so I think it is a recent
change.  I have not had a chance to bisect yet.
