While this aims to find existing VM corruption (i mean, in PG <= 17), this reproducer does not seem to work on pg17. At least, I did not manage to reproduce this scenario on pg17. This makes me think this exact corruption may be pg18-only. Is it possible that AIO is somehow involved here? -- Best regards, Kirill Reshke
