            Bug ID: 229235
           Summary: vt(4) of 11.2-RELEASE is broken with hardware
                    dependent problem.
           Product: Base System
           Version: 11.2-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: yasu@utahime.org

With the commit of r335510 releng/11.2 switched to -RELEASE. So I updated o=
ne
of my home server from 11.1-RELEASE-p11 to 11.2-RELEASE.

But when I rebooted I found OS boot messages are not displayed on console w=
hile
OS itself has booted successfully. To be exact,

1. BIOS message are displayed.
2. Boot menu of FreeBSD is displayed.
3. Kernel boot starts but after 'Booting...' no following messages are
displayed.
4. After OS has booted console stays unusable.

Kernel configuration is as follwing.

I tried GENERIC kernel but the problem still happened.

HWs are,

M/B: ASUS N3150I-C (https://www.asus.com/us/Motherboards/N3150IC/)
Display: EIZO FlexScan L565
(http://www.eizoglobal.com/support/db/products/model/L565)

M/B and display are connected with analog VGA.

I have another 11.1-RELEASE-p11 amd64 environment working as guest of
VirtualBox whose host is 64bit Windows 10. So I updated it to 11.2-RELEASE =
like
my home server in question. But in this case console worked fine just as it=
 was
11.1-RELEASE-p11. So the problem seems to be hardwear dependent.

I added above lines to /boot/loader.conf and rebooted system. Then all boot
messages are displayed and console works fine.

----------------------------------------------------------------------
# Load SysCons driver
kern.vty=3Dsc
----------------------------------------------------------------------

So I'm certain somthing is wrong with vt(4) of 11.2-RELEASE.
