[  111.513087] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun
Comment 1 harish.chegondi 2019-11-14 20:20:45 UTC
Until 5 months ago, this failure used to happen few times every month. In the last 4 months, there was only one failure. All these test failures happened on BYT platform. There are several other bugs with "FIFO underrun" dmesg warnings.

This test tests plane rotation with plane type "Overlay" and rotation of 180 degrees.
