What motherboard? What is the lspci output? Does baremetal Linux kernel boot
with VT-d enabled? Have you tried to boot without x2apic? ("x2apic=off" on Xen
hypervisor line)?

I don't think it's a kernel related problem, because the upgrade which broke it
was the hypervisor: from 4.0.1-rc3 to rc5. With rc3 I remember I had a similar
problem with iommu=1, a problem which I solved using iommu=passtrough.

>What motherboard?
Mobo is an Asrock X58 Extreme.

>Does baremetal Linux kernel boot with VT-d enabled?
Yes.

>Have you tried to boot without x2apic? ("x2apic=off" on Xen
hypervisor line)?
No, I will try as soon as possible.

I just tried with x2apic=off, but it didn't solved the problem :(

I believe even xen-4.0.0 does not work on ASRock X58 Extreme. I am running
SLES11.1 which runs xen-4.0.0. I have the same symptom. I tryied x2apic=off. No
difference. It seems this is a problem of mobo. Has anyone contacted ASRock?

Can you provide the serial output or 'xm dmesg' with 'iommu=verbose' as
bootline? I am curious to see whether we detect the DMAR (Intel VT-D chipset)
or if it is busted.

You did upgrade to the latest BIOS, right?

>I believe even xen-4.0.0 does not work on ASRock X58 Extreme.
It works (or at least it boots flawlessly), you just need to boot with
iommu=passthrough.

>Can you provide the serial output or 'xm dmesg' with 'iommu=verbose' as
>bootline? I am curious to see whether we detect the DMAR (Intel VT-D chipset)
>or if it is busted.
Yes, if the RS232 serial port does work. I will try as soon as possible.

>You did upgrade to the latest BIOS, right?
Yes, when I filed the bug some months ago. In the meantime they released some
new versions, I will try to upgrade the bios once more.

Please fix the xen command line, there's a typo in it: iommu=vergbose . It
should be "verbose", of course.

If ioomu=no is the same, it does help for me. So I think it does help for him
too.

So in the boot log, it says:

(XEN) [VT-D]dmar.c:524: RMRR address range not in reserved memory base =
bbeeb800 end = bbefffff; iommu_inclusive_mapping=1 parame
ter may be needed.

Did you try that parameter?

Second, for the Dom0 crash, can you decode the eip address to find where it
crashes? Here is how you can do it:
