[xen-unstable] Commit 2ca9fbd739b8a72b16dd790d0fff7b75f5488fb8 AMD IOMMU: allocate IRTE entries instead of using a static mapping, makes dom0 boot process stall several times.
Hi Jan,
After commit 2ca9fbd739b8a72b16dd790d0fff7b75f5488fb8 AMD IOMMU: allocate IRTE entries instead of using a static mapping, booting dom0 stalls several times.
Sometimes this results in RCU stall warnings from the dom0 kernel, hitting the "any" key, on normal or serial console, makes the boot continue for a while but it stalls several times.
(It also stalls on shutdown BTW)

AMD IOMMU disabled - No Perdev Intremap
Hi!
From other people posting to this list, I know that there has been a
bug related to the issue described in Xen Security Advisory 36 that
disables iommu for some AMD users like me.
However, even when passing "iommu=no-amd-iommu-perdev-intremap" it
still disables i/o virtualisatoin. Related Xen dmesg output:
(XEN) IVHD Error: Invalid IO-APIC 0
(XEN) AMD-Vi: Error initialization
