Disabling IOMMU did indeed enable us to boot.

Title:
  hpsa driver causing kernel panics on HP ProLiant DL385p Gen8

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Doing regression testing on Ubuntu 14.04.4, we've found a big one: An
  HP ProLiant DL385p Gen8 kernel panics on startup with the default
  kernel for that version (4.2.0-27-generic). 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.
