[  491.071872] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe C FIFO underrun

Note we sometimes also hit the crc mismatch on this test:

https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3733/fi-cnl-y3/igt@kms_pipe_crc_basic@suspend-read-crc-pipe-c.html

this is bug 103191

Hello, the following test cases are working correctly on CNL for three weeks, could we close this bug as fixed?

==================
Test Cases

it seems they are back :/
