Then compared 'iommu'-containing commits (as this OID hangs) and discovered ec8d60f0d9b762880482e39f567db552c152d3a2 by kib@, which exposes the value. = This commit is only present in releng/14.2, so I believe it's the trigger. Howev= er, most likely no more than a trigger -- not root cause. --=20 You are receiving this mail because: You are the assignee for the bug.=
