--- Comment #15 from Radhakrishna Sripada <radhakrishna.sripada at intel.com> ---
One thing that I would do to check if it is a fbc related flicker is to boot
with command line parameter i915.enable_fbc=0 and check if the flicker happens.
Since you no longer see the original flicker, I would suggest to raise a
different bug for the new flicker that you are observing with relevant logs.
@Nicholas: What is the current drm debug level that you are using? can you do
"echo 0x6 > /sys/module/drm/parameters/debug" and see if you are still
observing FB logs?
I do not see any down sides by adding to the quirk table. Jani Nikula can you
confirm?
