>Description:

The uefi boot (e.g. on install images) shows a countdown untill the
default option is chosen. This countdown is invisible though. The screen
displays a static:

 Option ... will be chosen in #

(where # marks the cursor), no updates happen, and after a while the option
is chosen.

>How-To-Repeat:

Boot the uefi install image

>Fix:
n/a

 I need to check more carefully for details, but it seems that this
 either does or does not occur depending on the UEFI implementation in
 question.

 I see it both in Virtualbox and on an Acer Aspire V - whatever that is
 worth.

Subject: PR/53292 CVS commit: src/sys/arch/i386/stand/efiboot
Date: Wed, 16 May 2018 19:53:54 +0000

 Module Name:	src
 Committed By:	jakllsch
 Date:		Wed May 16 19:53:54 UTC 2018

 Modified Files:
 	src/sys/arch/i386/stand/efiboot: eficons.c

 Log Message:
 During awaitkey(), move the cursor back to the beginning of the
 countdown with '\b' only after waiting.

 Some UEFI implementations have a destructive/erasing backspace,
 and will not show the countdown if we move the cursor back before the
 wait.

 My ThinkPad T430 w/ Lenovo's UEFI exhibited this whiteout-backspace,
 while my Gigabyte Brix GB-BXBT-2807 did not.

 Should fix PR #53292.
