I suspect that your dom0 kernel is missing a workaround for a bug/issue in
the Linux block-device code. I would recommend building a 2.6.18 kernel from
xen-unstable.hg repository, or at least rebuilding your Debian dom0 kernel
with the file arch/i386/kernel/swiotlb-xen.c replaced with the version from
the xen-unstable.hg repository (or if that doesn't compile, take the version
of the function __sync_single() and copy that into Debian's swiotlb-xen.c).
