Issue #574 has been reported by Alicja Michalska.
---------------------------------------- Bug #574: Stack corruption in romstage on Intel platform (ADL-N) with recent builds https://ticket.coreboot.org/issues/574
* Author: Alicja Michalska * Status: New * Priority: Normal * Category: coreboot common code * Target version: none * Start date: 2024-12-17 * Affected versions: master ---------------------------------------- While building from master (testing CB:85609), I've noticed CBMEM complaining about stack corruption. Older build made a ~month ago did not experience the same issue. Maybe caused by Xeon-SP refactoring?
