Title:
  Using "splash" Linux boot option causes IPMI console view to blank

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I'm using a set of blade servers with SuperMicro BIOS and IPMI console
  viewing capabilities.  I use the Ubuntu netboot options with a PXE
  server to install.

  I've installed Ubuntu 12.04 and 14.04 on these systems, and everything
  works great.

  However, when I install Ubuntu 16.04 (and this is true both if I
  upgrade from Ubuntu 14.04 with do-release-upgrade AND when I install a
  fresh copy directly via the Ubuntu 16.04 netboot image via PXE), then
  the install works but when I reboot the IPMI console is completely
  blank: no cursor, no text, no typing shows anything.

  I can still SSH to the system (except of course the default netboot
  install doesn't include sshd for some bizarre reason so I had to play
  some tricks and rerun the install multiple times :-/).

  After a lot of experimentation I discovered that if I edit the
  /etc/default/grub file and remove the "splash" setting from
  GRUB_CMDLINE_LINUX_DEFAULT variable and re-run update-grub, then
  things worked fine and I was able to boot properly without losing
  access to the IPMI console.

  One more note: this is definitely a kernel issue because when I choose
  the older 14.04 kernel (3.13 or similar) from the boot menu on the
  system I upgraded from 14.04 to 16.04, with the "splash" setting still
  in the grub config and no other changes (so userspace is still all
  16.04), I had no problems with the IPMI console viewer.
