I run a bisect session, and narrows it down to following commit: commit d74169ceb0d2e32438946a2f1f9fc8c803304bd6 Author: Dimitri Sivanich Date: Wed Apr 24 15:16:29 2024 +0800 iommu/vt-d: Allocate DMAR fault interrupts locally The Intel IOMMU code currently tries to allocate all DMAR fault interrupt vectors on the boot cpu. On large systems with high DMAR counts this results in vector exhaustion, and most of the vectors are not initially allocated socket local. Instead, have a cpu on each node do the vector allocation for the DMARs on that node. The boot cpu still does the allocation for its node during its boot sequence.
