Control: retitle -1 5GHz WiFi does not work with vc4.ko on RPi4 and 4K display
Control: tags -1 + upstream
Control: severity -1 normal

It turns out that the reported symptom happens with 5GHz Wifi
and 4K display resolution at 30 Hz refreshing rate.

Since the condition is rather limited, I lowered severity to normal.
This is an upstream issue.
It is being discussed at "linux-rpi-kernel" mailing list.

Best regards, Ryutaroh Matsumoto
