problems with runnung 32bit gutsy domUs on 32bit gutsy dom0 xen server

[Tomoki Taniguchi]

I have a few gutsy based xen servers.
of these a couple are newly purchased 64-bit dual-core based servers
running gutsy amd64 xen server.
the others are i386 based servers running gutsy i386 xen server. (used
to run feisty i386 xen server)

The AMD64 based xen servers have no problems running 64bit gutsy domUs.
But when i try running a 32bit gutsy domUs on i386 xen servers, it
hangs at the startup.
These same i386 xen server have no problem running 32bit feisty domUs.

I am thinking there is some sort of problem with running 32bit gutsy on xen.
any way to fix this?

TIA,
Tomoki
