This is a CRC mismatch issue, I can sometimes reproduce on a HSW Harrishbeach laptop that has a PSR capable display.

    tests/kms_psr_sink_crc: Do not test sink crc

    eDP sink crc reads use vblank interrupts that cause PSR exit and
    therefore makes them unsuitable for PSR testing. Besides that, reading
    sink CRC via the AUX channel for testing when the HW also is most likely
    is going to be using AUX channel is a recipe for inconsistent test
    results. Thirdly, CRC's have been seen to be noisy/inconsistent across
    sinks. We tradeoff the ability to validate what the sink is displaying
    for correctness.

    We also make use of source PSR status register to check whether HW tracking
    triggered PSR exit upon an exit event.
