The discussion on how to fix the issues has been stagnant for a long time, see the Bugzilla below and: https://patchwork.freedesktop.org/patch/170429/
After only changing display cable the result of my machine went from always failing to hit a WARN. This is also illustrated on CI-shards, where the shard-apl flip-flop between pass and WARN and the shard-kbl always fail. This made me realize that the THRESHOLD_PER_CONNECTOR also needed to be updated, while previous discussion only touched the THRESHOLD_TOTAL. As discussed in provided links the motivation for this test is to discover big anomalies in edid timings, but with the current tight thresholds we are hitting the issues too often. V2: increased thresholds further after patchwork results.
