<3> [140.850285] [drm:wa_list_verify [i915]] *ERROR* rcs0 workaround lost on before reset! (b118=0/0, expected 200040, mask=200040)
Even more confusing is that it stopped occurring. Still the same machine (icl6).
Failure in reading; it has failed twice now on iclb3.
Passed on iclb5, iclb6, iclb7 so far. It could just be that one machine... Fits in with the pre-production theory.
And now it is appearing out of the blue on BAT fi-icl-u3.

That at least appears to have been a bad merge now fixed up by Tvrtko.
