            Bug ID: 241036

           Product: Base System

Final state of efifb

Running the 12.0-RELEASE installer in a UEFI VM sees a weird behaviour. We =
get
to
the line "smbus0: <System Managmeent Bus> on intsmb0" and that's the last l=
ine
displayed. I thought initially the VM was frozen, but it turns out (thanks =
to
RhodiumToad in IRC) that it's just switching over to serial at that point.

I checked backwards and forwards when I first noted this, and it started wi=
th
11.3, and 13-current also exhibited the behaviour. A notable change between
11.2
and 11.3 is that in the (working) 11.2 installer, the Beastie logo shows up=
 in
colour, but in the (not working) 11.3 installer he is monochrome.

I've added a screenshot showing the console in its final state, and I've ju=
st
taken a couple more as the notion of immediately switching to the serial
console
occurred to me. I'll add those presently.

This might be related to BZ#237385 but there are differences. Primarily, I'm
not
specifying anything special for the install environment.
