(XEN) DMAR: Request device fault addr 3f7620000, iommu reg = ffff82c000504000Īlso, I noticed increased boot time and a 30 sec. (XEN) DMAR: reason 02 - Present bit in context entry is clear The SATA controller should work under Dom0 and DomU. Install a PCI-E SATA controller based on the Marvell 88SE9125 chipset (or other chips in the 88SE91xx family), boot QubesOS with IOMMU. If it's the primary SATA controller in the system, it's likely that Qubes won't even start. Without a workaround, the Marvell 88SE91xx SATA controller family won't work. But Xen didn't incorporate a similar fix, however, a workaround using Xen option pci-phantom is possible. The Linux kernel included a quirk workaround for all known controllers affected by this bug. All operating systems and hyperviors are affected. Xen, IOMMU, Marvell 88SE91xx SATA controller(s)Ī Marvell hardware/firmware bug affects multiple devices in the Marvell 88SE91xx family, the bug is responsible for generating invalid DMA reads/writes, preventing their proper operation when IOMMU in enabled.
