Precondition:
--------------
Boot with kernel boot command lines: i915.enable_guc_loading=2

tar -xvf SynMark2.tar.gz
2. From, Terminal 1:
startx

cd SynMark2
sudo -E ./synmark-test.sh

Actual result:
--------------

ended and returns errors:
intel_do_flush_locked failed: Input/output error
libGL: OpenDriver: trying /opt/X11R7/lib/dri/tls/i965_dri.so
