[Bug 1756359] Re: Rebooting goes into infinite loop on Surface Pro 3

[Mathieu Trudel-Lapierre]

Could you check in the devices' firmware Setup utility, if there is a
feature called "Boot Order Lock" that is enabled?

Title:
  Rebooting goes into infinite loop on Surface Pro 3

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  GRUB-EFI-AMD64 installed during normal system updates.

  Ten minutes later, Surface Pro 3 froze up, possibly from unrelated
  issue. Hard rebooted computer using power switch.

  Red Surface Pro screen shows at start of reboot. Black screen with
  three lines of text flashes by too fast to read. Surface Pro screen
  shows again. Black screen shows again. Process repeats forever.

  Was able to shut of computer with power switch. Restarted computer,
  pressed ESC to go to BIOS. Turned off Trusted (something) Management
  (TPM). Machine booted normally.
