For PCI xHC controllers the spec lists possible causes as: host controller PCI parity error, PCI Master Abort, PCI Target Abort. But DMA issues also possible cause, especially as log shows DMAR problems right after this. Any chance you could bisect this on upstream kernel? --=20 You may reply to this email to add a comment.
