fbd0 / vt(4) console, no longer coming up after 14.2-RELEASE upgrade?

Hi folks,

I'm not sure how to report this - please let me know and I'll follow
up accordingly.

I've been running 14.x on my Intel NUC (NUC6i3SYH Intel Core i3-6100U)
as a home server for about a year now, flawless.
Last night I did an upgrade from 14.1-p6 to 14.2-p0. It didn't go 100%
clean, on the first call to
# freebsd-update fetch install ;  freebsd-update upgrade -r 14.2

I got errors about a failed checksum:

Fetching 1861 files...

29c8fdfdb5d2d8a8cb33bacfee74154c08f9a7384d6a397f73d4fcdd9f20a9b2 has
incorrect hash.

These went away on a second run.
It looked good except from a few changes on /boot/devices.hints that
might be relevant, so I rebooted.

After entering the GELI password and selecting the multi-user boot, I
didn't get a login prompt.
I don't use the console for anything other than booting up and
entering the GELI password, so I'm not stuck.
The box is accessible via IP so I was able to gather a bit more info.

My screen is showing the usual boot-up dmesg up to:

(...)

Reading the readmining dmesg buffer after connecting to SSH, I see the
following:

[7] VT: Driver priority 0 too low. Current 101
[7]  fbd0: not attached to vt(4) console; another device has precedence (err=17)

After those, it's all about the NICs/bridges/ipfw coming online.

I'm happy to provide more information and help troubleshoot this, as
it might be more critical to other people.

Thanks in advance,
