[Bug 1666068] [NEW] Linux kernel reboots on execution on the SuperMicro MBD-X11SAE-M in EFI mode

[fedorowp]

Public bug reported:

The Problem
-----------

When booted in EFI mode, 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, the machine reboots upon
invocation of the 'boot' command in grub, following the kernel and
initrd being loaded via kernel16 / initrd16.  (See Bug #1666063 for why
kernel16 / initrd16 is required.)

This bug does not occur when booted in BIOS (non-EFI)

Booting in EFI mode is required for the installed system to boot from
NVMe drives.


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

1. Ubuntu 16.10 Server installer running from USB 3.0 stick booted in EFI mode
[Grub version 2.02~beta2-36ubuntu11]

2. Ubuntu 17.04 Alpha 1 installer running from a different model USB 3.0 stick booted in EFI mode
[Grub version 2.02~beta3-3ubuntu2]

3. Ubuntu 16.04 LTS LiveUSB running from a a different model USB 3.0 stick booted in EFI mode
[Grub version 2.02~beta2-36ubuntu3]

4. Ubuntu 16.10 LiveCD booted from a USB 2.0 Asus Blu-Ray drive


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

1. All three Server Installers and the LiveCD have been verified to boot
properly in EFI-mode on a Toshiba laptop when plugged into its USB 3.0
port.

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

3. Brands/models of USB sticks used for testing:
Kingston HyperX 64GB
Kingston DataTraveler G4 8GB
Kingston DataTraveler 100 G3 8GB

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

5. Ubuntu 17.04 Alpha 1 installed and runs normally on the hardware in
BIOS mode with the Grub workaround described in Bug #1666063.  NVMe
devices cannot be used as boot devices, so a pair of USB 3.0 sticks
running a RAID-1 was used as the boot device for this BIOS mode test.
This is hardly ideal for production use.


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)

** Affects: grub2 (Ubuntu)
     Importance: Undecided
         Status: New
