Not sure if this is IGT only, so pointing it here, please move otherwise.
On CNL test igt at kms_sink_crc_basic is giving the output:

IGT-Version: 1.20-g2a1c1c0 (x86_64) (Linux:
4.14.0-drm-intel-qa-ww47-commit-79ca54c+ x86_64)
Test requirement not met in function assert_color, file
kms_sink_crc_basic.c:56:
Test requirement: igt_sysfs_scanf(dir, "i915_sink_crc_eDP1", "%4x%4x%4x", &r,
&g, &b) == 3
Sink CRC is unreliable on this machine. Try manual debug with
--interactive-debug=no-crc
Last errno: 9, Bad file descriptor
