Re: [Xen-devel] Option iommu=1 causes hypervisor to start debugger

[Alexia Benington <alexbenington@xxxxxxxxx>]

I was referring to the fix titled "ioemu: fix PCI ROM handling problem
in passthrough". Seriously, I don't even know if the problem is
related. Just trying something because I'm totally clueless now.

I've attached the lspci. Let me know if you need more info. Will be
glad to provide.

Thanks guys.
