[Bug 1666082] Re: Linux kernel reboots on execution from Server Install CD in CSM/BIOS mode using SuperMicro MBD-X11SAE-M imotherboard

[Phillip Susi]

Booting the installer in bios mode uses LILO rather than GRUB, but this
isn't a problem with LILO either... it's just a default setting on the
cd image.

Title:
  Linux kernel reboots  on execution from Server Install CD in CSM/BIOS
  mode using SuperMicro MBD-X11SAE-M imotherboard

Status in Ubuntu:
  New

Bug description:
  The Problem
  -----------

  Using a SuperMicro MBD-X11SAE-M motherboard, (which uses the Intel
  C236 chipset,) running firmware version 1.0b 03/24/2016 - latest at
  time of filing this bug, when booted in BIOS/CSM mode, the machine
  locks-up - no disk activity, no caps lock response, black screen --
  upon selecting "Install Ubuntu Server" due to the vga=788 kernel
  command-line option.

  This problem does not occur with the LiveUSB/LiveCD version, as it
  does not by default invoke the Linux kernel with the "vga=788" option.

  
  Work-Around
  -----------

  Remove the "vga=788" kernel command-line option to enable the
  installer to work normally.

  This behaviour and work-around have been tested under the following
  problem scenarios:

  
  Problem Scenarios
  -----------------

  1. Ubuntu 16.10 Server installer running from USB 3.0 stick booted in
  BIOS (non-EFI) mode

  2. Ubuntu 17.04 Alpha 1 Server installer running from a different
  model USB 3.0 stick booted in BIOS (non-EFI) mode

  3. Ubuntu 17.04 Alpha 1 Server installer running from a USB 2.0 Asus
  Blu-Ray drive booted in BIOS (non-EFI) mode

  
  Additional Notes
  ----------------

  1. Installer sticks were created by dd'ing the ISOs to the memory
  sticks.

  2. Brands/models of USB sticks used for testing:
  Kingston HyperX 64GB
  Kingston DataTraveler G4 8GB

  4. All installer and LiveUSB tests where tried using both the USB 3.0
  and USB 3.1 ports on the SuperMicro motherboard.

  
  Hardware
  --------

  Motherboard: SuperMicro MBD-X11SAE-M Motherboard
  Processor: Intel Xeon E3-1225 v5 SkyLake 3.3 GHz
  RAM: 2x Kingston ValueRAM 16GB (1 x 16G) DDR4 2133 Server Memory ECC DIMM
  SSDs: 2 Samsung 960 EVO M.2 500GB NVMe SSDs (One installed into motherboard socket, one installed into SYBA M.2 PCI-e To PCI-e 3.0 x4 Card)
