[Bug 1448668] Re: Grub menu hangs on down arrow press with USB keyboard on cold boot

[Clément R]

Well, I'm encountering this exact issue as well!

I've had a dual boot on two hard drives for a while (Windows 10 / Linux
Mint), and recently changed my GPU. After upgrading the drivers on both
OS, GRUB seems to get stuck on any key I press. Meaning that Enter
works, but pressing down goes directly at the last index, and GRUB
doesn't respond then.

Also if I press c, the command window open, and a bunch of "ccccc" are
typed in the prompt. Not undefinitely though (as I first expected). It
lasts just for one second. Then whatever letter I type, it also gets
spammed for a second. Mening that the console is unusable, but not
frozen like the GRUB menu.

Another strange aspect: sometimes, this problem does not happen anymore!
I couldn't find any pattern, but I've been able on rare occasions to use
GRUB with no issue. I then thought I somehow fixed it, but on the next
boot the bug was still there…

What I've tried so far, with no success:
- Switching my USB keyboard from a USB3 to a USB2 port
- Disabling the Legacy USB support in the BIOS
- Disabling XHCI in BIOS
- Pressing ESC (as mentioned above) just freezes GRUB (and so does Page Down and shift)
- Purging and Re-installing GRUB (through boot-repair)

I also noted that, when booting from a live-usb, the GRUB there worked
with no issue.

The next step for me now is updating my BIOS. It's a bit scary I must
admit (It already took me all morning and 3 tries today to reinstall
GRUB, just to get back to point zero!).

Anyway, if it can help solve this issue, here are the data relative to my BIOS from the command "sudo dmidecode -s bios-release-date": https://paste2.org/2x7kv61L
And here is the last BootInfo log from boot-repair (sda is the windows drive, sdb linux mint, and sdc is just a storage drive): https://paste2.org/9pNb5WsI

Title:
  Grub menu hangs on down arrow press with USB keyboard on cold boot

Status in grub2 package in Ubuntu:
  Confirmed

Bug description:
  I installed Windows 8.1 64-bit, then installed Ubuntu 15.04 bit, both
  in UEFI mode.

  When booting, I am presented with the usual GRUB menu, with Ubuntu
  preselected at the top. If I press enter, Ubuntu loads. If I press
  arrow down (just once) to move down the menu toward the Windows entry,
  the highlighted entry skips rapidly to the bottom of the list and GRUB
  hangs and becomes completely non-responsive. Cycling the power or
  pressing reset is required.

  This only happens on a cold boot, i.e. if the computer was off prior
  to going to the GRUB menu. If I get to the GRUB menu via pressing the
  "reset" button, or booting into Ubuntu and choosing "restart", the
  arrow keys work fine in the GRUB menu.

  In addition, this bug only occurs with my USB keyboard (Logitech
  K120), not with my PS/2 keyboard (Logitech Deluxe 250). Trying
  different USB ports doesn't help.

  Summary:

  What happened: GRUB hangs if I press cursor down when using a USB keyboard after a cold boot
  What should happen: I should be able to use arrow down to move down the GRUB boot menu to the entry I require
  To reproduce: Install Windows 8, then install Ubuntu 15.04. Turn off power. Turn on power, boot computer, at GRUB menu press arrow down.

  Presumably all hardware info is attached to report, but just to be
  sure: I'm trying to boot off a GPT partitioned 500GB SSD, and have a
  GA-Z97-D3H motherboard.

  If you need any further information, just ask!
