Bug description:
[ Impact ]
The desktop does not come up and the screen stays blank when using
'dtoverlay=vc4-kms-v3d' on a Pi 4 (as is the case in raspi desktop
images). If the desktop does come up, playing video freezes the
desktop and/or the system. The kernel log shows loads of WARNINGs and
potentially firmware errors.
[ Test Case ]
Use a raspi desktop image, play video (youtube or VLC), move windows
around, switch to and from fullscreen video playback.
[ Where problems could occur ]
The fixes are all local to the VC4 driver so (new) issues should only
show up when that driver is in use. Potential problems are UI freezes,
kernel stalls and crashes.
[ Original Description ]
Workaround
----------
With media which you will boot off of change the line dtoverlay=vc4-kms-v3d
to dtoverlay=vc4-fkms-v3d in /system-boot/config.txt
Original Description
--------------------
Have a HDMI display w/o audio hooked up to this RPI4B.
With the latest kernel update the screen does not turn on due to this.
