--- Comment #5 from erhard_f@mailbox.org --- Created attachment 140950 --> https://bugs.freedesktop.org/attachment.cgi?id=140950&action=edit html-summary from 'pigllit run sanity' (18.0.5)
Same test failures with mesa 18.0.5. So I guess it's piglit itself failing, as at the time I did first piglit tests with 18.0.x on ppc64 (see bug #105463) the sanity tests passed.
