Hello Edgar,
Thank you for the testing.

You could uncomment //#define DEBUG_DT in domain_build.c, rebuild and
paste the log here?

It should not matter, unless the interrupt controller is used to
describe some interrupts in device-tree.
Is this node used later in the DT?

I would try to fix it in Xen 4.7 if the patch is simple. Otherwise we

Was PCIe working on Xen 4.6? If yes, it's the regression and we could
consider it as a blocker for the release (CC Wei for that).
