Title:
  PCI passthrough of LSI card fails

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Using ESXi version 6. With an Ubuntu 14.04 guest, passthrough works
  fine. With Ubuntu 15.10, the card is passed through but boot is slow
  and there are time outs reporting in logs. Disk devices do not show up
  in guest OS. This can also be seen during a fresh install/live CD boot
  of Ubuntu 15.10 vs 14.04.
