            Bug ID: 209275
           Summary: Cannot utilize both serial and efi console with UEFI
                    booting
           Product: Base System
           Version: 10.3-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs at FreeBSD.org

I cannot get dual consoles for boot running in FreeBSD 10.3-RELEASE using the
UEFI boot.

When my settings are:

/boot.config:
     -D -S115200

/boot/loader.conf:
     boot_multicons="YES"
     boot_serial="YES"
     comconsole_speed="115200"
     console="comconsole,efi"
     geli_ada0p4_keyfile0_load="YES"
     geli_ada0p4_keyfile0_type="ada0p4:geli_keyfile0"
     geli_ada0p4_keyfile0_name="/boot/encryption.key"
     aesni_load="YES"
     geom_eli_load="YES"
     geom_eli_passphrase_prompt="YES"
     vfs.root.mountfrom="zfs:zroot/ROOT/default"
     kern.geom.label.gptid.enable="0"
     zpool_cache_load="YES"
     zpool_cache_type="/boot/zfs/zpool.cache"
     zpool_cache_name="/boot/zfs/zpool.cache"
     zfs_load="YES"

GELI passphrase shows in both consoles, but only accepts input from keyboard
(at least only the enter key.  It seems as if it might get some sort of other
input from the serial console since the passphrase isn't correct when mounting
occurs, and I have to enter it again from they keyboard OR serial console at
this phase).  Beastie menu shows on both, but doesn't have the auto-timeout for
boot, and only accepts input from keyboard.  Login works from both consoles.


When my settings are the same above except for the line

"console=comconsole" instead of "console=comconsole,efi"

All console output/input works fine from the serial port, but nothing appears
on the monitor until actual OS starts to boot. Autoboot from the beastie menu
works fine in this mode, but GELI passphrase and beastie menu don't appear on
the monitor.


When my settings are the same above except for the line

"console=comconsole, vidconsole" instead of "console=comconsole,efi" (like
before the efi booting)

I get "console vidconsole is invalid!" and everything else is the same as if I
just had the comconsole as above.
