ISTR that iscsi doesn't work when running a 64-bit kernel with a 32-bit userspace. I remember someone offered kernel patches to fix it, but I think they were rejected. I haven't messed with that stuff in many years, so perhaps the userspace side now has accommodation for it. It might be something to check on.
