there is a IOMMU bug HP is debugging and for now you can disable IOMMU and it should boot as well as should work fine. Once HP will identify fix and release it we will integrate into Ubuntu 16.04.

The server's display (see screen shot taken via its BMC's remote KVM) shows a kernel panic that seems to implicate the hpsa driver. This server boots and installs every Trusty release through 14.04.3 (with a 3.19.0-25 kernel) just fine. I'm attaching log files from a 14.04.1 installation so that you can have some hardware information, and a screen shot of the kernel panic in 14.04.4. We (the server certification team) have access to the server for a limited period. Normally it's in OIL.
