Any idea what can be result of such weird behavior?
My current guess is AP CPUs do not see initialised memory for _car_region_start .. _end. That region is set up using fixed MTRRs in low memory and probably not synced between cores so early in romstage.
Ugh. Why do we allow the APs to run through all these stages? Is this for parallel node memory training? Can we ring fence where the APs actually run better?
