In CNL we're getting this message in our FF tests.
[ 309.667455] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU
pipe A FIFO underrun
It have been appearing at least a couple of time in the dmesg by cycle, and
though the system capture the warns while executing a specific test, it don't
seems to be triggered by that test, since repeating the test various times
won't give it.
Some of the test that have seen the messages at least once over the week:
igt@gem_exec_flush@basic-wb-prw-default - commit-1a0d67e
igt@gem_sync@basic-each - commit-1a0d67e
igt@gem_exec_create@basic -commit-807db75
