Upgrade to UCM 8.5 fails to boot

We're upgrading from 6.1.5 to 8.5 on MCS-7825-H3's. The install to the inactive partition happens without errors but when we switch versions and the server reboots it hangs shortly after the Grub menu. Attached are screen shots of the when the server stops booting. Even the 8.5 recovery disk fails to boot. Using the 6.1.5 recovery disk allows us to switch partitions to get back to a working 6.1.5. I have tried both the version shipped from a PUT order and the latest down load version and both do the same thing. We have a TAC case open but I was wondering if anyone on the forum has run in to this before.

Thanks!
