So it isn't "the rail can't follow", it's the gfx rail sitting at or above the highest level in the table while the firmware calibrates. CLX being a current limiter, a limit entry would be my guess, but that's firmware territory. If the CRD still fails after sync_state, gfx.lvl being held at the top level by something else would be the first thing I'd check there. Oleg
