https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=293382 --- Comment #65 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to Kristofer Peterson from comment #64) So we have some lead. There is a public errata document https://docs.amd.com/v/u/en-US/58251_PUB_1.30 Look for the errata 1567 Instruction State May be Corrupted during REP CMPSB or REP SCASB Description During the execution of a REP CMPSB or REP SCASB, the instruction state may be corrupted. Potential Effect on System Unpredictable system behavior Suggested Workaround System software may contain the workaround for this erratum. Fix Planned No fix planned It only says something about cmps and scas, not about movs. But this is very close. Also, the revision is from July 2025, I did not found anything newer. -- You are receiving this mail because: You are the assignee for the bug.home | help
