In all cases the vc4 HDMI errors are recurring and take multiple forms even on the same machine.

[Bug 1945842] Re: Newer kernel still has no display w/ KMS enabled
I am also seeing this after an automatic update from linux- image-5.11.0-1017-raspi to linux-image-5.11.0-1019-raspi. The display output is lost very early on in the boot process. The only way I could get round it was to roll the kernel back to 5.11.0-2017.
