Hi, The latest Xen unstable (c/s 19984) crashes when with iommu=1 (in Grub configuration) I attach here the screenshot. Any clue on how to fix this? (My chipset supports VT-d) Thanks, J _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

But we don''t have the platform like yours. It''s strange 0:2.0 accesses a very big address 0xffffff000. Pls try to add iommu_inclusive_mapping=1 in kernel line in grub.
