On restore 32bit PV guest crashes on x64_86 host, while x64_86 PV guest
works as expected.
Bisecting of upstream kernel shows following offending commit:

a1fcd6e xen:p2m: Create entries in the P2M_MFN trees's to track 1-1 mappings
39fc738 xen/setup: Ignore E820_UNUSABLE when setting 1-1 mappings.
But the more I look at this I don't think those patches will help here at all.
This looks like a completle new failure. Let me try it on my box tomorrow
and see how it works out.

I tried to repro the issue but I couldn't.

I tried this with 2.6.39-rc6 and could not reproduce this. Does it work
for you with 2.6.39-rc6? Or is it _only_ failing with 2.6.38?

It's failing with 2.6.39-rc6 as well. And 2.6.38 with suggested patches
as well.
But since I do like fast builds, I've used fast PC with 2 NUMA nodes at
least and
it turns out that the bug is not reproducible on PC with only one cpu
(HPZ800
1 socket config). So you can reproduce it if you try a PC with at least
2 cpus
nodes.

Hmm, the guest is a single CPU one, so perhaps you are hitting a hypervisor
issue. What happens if you turn NUMA off on the hypervisor line?

Ok, I've an old IBM x366 that has four sockets - that should do it -
but will have to wait till next week when I am back from traveling.

Looks like removing numa=on from hypervisor init line helped, guest
stays alive after restore.
