            Bug ID: 191564
           Summary: [vt] UEFI boot shows that screen is not cleared as
                    kernel starts
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: amd64
                OS: Any
            Status: Needs Triage
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: emaste@freebsd.org

screenshot of UEFI vt(4) boot

The UEFI loader uses UEFI's console services for I/O; the vt_efifb driver takes
over for vt(4)'s framebuffer when the kernel boots, but does not clear the
screen first, so some of the previous output remains on screen until it is
scrolled off.

See the attached screenshot - the loader's output finished with "Start @ 
0xffff...." at the bottom, and the kernel's output started with "GDB: no debug
ports present" at the top.
