Hi,
Well, just tried what you suggested, and here are the
results:
* If i comment the 'clear_fault_bits()' call - then Xen boots ok,
with iommu=1
The strange thing, is that after it booted one time ok (with
the second patch), then it continued to boot ok, even if i reverted the second
patch.
The relevant lines in the log are:
(XEN) clear_fault_bits:
CAP_REG=0xc0000020630270
(XEN) clear_fault_bits:
CAP_REG=0xc0000020630260
(XEN) clear_fault_bits:
CAP_REG=0xc9008020e30260
(XEN) clear_fault_bits:
CAP_REG=0xc9008020630260
Anyway, here is the full Xen log, with the
first patch (print cap's) applied:

Can you please apply the above patch and send us the entire

(I don't have the same host, so I can't try it
myself.)

Problem: Xen 3.4 fails to boot on Dell e6400, with iommu=1
Hi,
I am trying to use xen 3.4 on a Dell E6400 machine. But,
when i try to boot xen with a 'iommu=1' parameter in the boot line, Xen
fails to boot. I have also tried to boot with and without the
'iommu_inclusive_mapping' boot option, but it didn't seem to help at
all.
Does anyone knows how to solve this issue?
