            Bug ID: 235550
           Summary: i915kms.ko disables console view
           Product: Base System
           Version: 12.0-STABLE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: bsd@volki.at

When i915kms.ko is loaded, no matter whether it is the one from the base sy=
stem
(/boot/kernel/i915kms.ko) or from the drm-legacy-kmod (version g20190109) p=
ort
(/boot/modules/i915kms.ko), the system consoles can no more be seen. Apart =
from
the display problem, the consoles remain functional. Text input is still
possible.

The error may be caused by either i915kms.ko or /boot/kernel/drm2.ko, which
seems to be loaded automatically with i915kms.ko.

When i915kms.ko is loaded manually from the console, the screen gets black.
When it is loaded automatically on xinit, the console is hidden anyway.
Switching to the console with ctrl-alt-F1/F2... leads to a distorted screen.
Switching back to X works properly. When X terminates, the screen gets blac=
k.

GPU is Intel Haswell 4600 (part of Intel Core i7-4790S CPU).

See my comments in #217689 for further details. As opposed to the
classification of that previous bug, the issue is not X11 related, as it ca=
n be
observed without X11 as well.
