I think I'll debug this a bit later - unfortunately, now don't have

yesterday ? Will Ian accept it?

I think that's OK: it looks like that on your board for some reasons
when UIE is set you get irq 1023 (spurious interrupt) instead of your
normal maintenance interrupt.
But everything should work anyway without issues.
This is the same patch as before but on top of the lastest xen-unstable
tree.

That's right, the maintenance interrupt handler is not called, but it
doesn't do anything so we are fine. The important thing is that an
interrupt is sent and git_clear_lrs gets called on hypervisor entry.

Hello Andrii,
we are getting closer :-)
It would help if you post the output with GIC_DEBUG defined but without
the other change that fixes the issue.
I think the problem is probably due to software irqs.
