[Xen-users] XEN hypervisor crash when using no-amd-iommu-perdev-intremap

[Frank Wilson <fajwilson@xxxxxxxxx>]

Hi,

I get a crash when booting with the no-amd-iommu-perdev-intremap
option, which I am using to try and enable IOMMU on my AMD FX
8320/Asus Crosshair Formula V (BIOS rev 1703) system.

Any one know why this happens?

I'm attaching the console log. Here is the error:
