Comment 2 Chris Wilson 2019-09-12 19:50:02 UTC

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.

Comment 3 Francesco Balestrieri 2019-09-30 05:47:15 UTC

Occurs on all ICL machines every other day or so, setting priority to high.
