Just in case it turns out to be relevant, this is with iommu enabled. No DMAR errors in this run, but I have seen 16:42 ickle : <3> [69.430006] DMAR: DRHD: handling fault status reg 2 16:42 ickle : <3> [69.430050] DMAR: [DMA Write] Request device [00:02.0] fault addr 44000 [fault reason 07] Next page table ptr is invalid recently on icl, so worth remembering.
Occurs on all ICL machines every other day or so, setting priority to high.
